How to use Outlook groups to collaborate over email

What are Outlook groups (Microsoft 365 Groups)?

An Outlook group is Microsoft's shared workspace for a team, built around email but bundling far more than an email list. When people say "Outlook groups" they almost always mean Microsoft 365 Groups, the same object that also powers Teams, SharePoint, and Planner behind the scenes. Creating one group gives a set of people a shared inbox they can all read and reply to, a shared calendar for the team's events, a files library backed by SharePoint, and a shared OneNote notebook, all under one name and one email address. It is Microsoft's answer to the common situation where a project team or department needs a single place to discuss things and a single set of shared resources, rather than a scatter of personal inboxes and forwarded threads.

The distinction worth holding onto from the start is that a group is a collaboration container, not just a mailing address. A traditional distribution list only forwards a message and then forgets it; there is no shared record, no calendar, no files. An Outlook group keeps the whole conversation in a shared inbox that any member can scroll back through, so someone who joins in month three can read what was discussed in month one. Because every group is backed by the same Microsoft 365 plumbing, the email, files, and calendar all stay in sync with one membership list: you manage one set of members and they get access to everything the group owns.

This guide walks through the whole thing for the two people who search for it most: someone asked to set up a group for their team, and someone added to a group who wants to email it, read its conversations, and use its calendar and files. We will cover creating a group, adding and removing members, public versus private, sending mail to the group and following its conversations, the shared calendar, files, and notebook, how groups differ from distribution lists, shared mailboxes, and Microsoft Teams, joining and leaving, the differences between new Outlook, classic Outlook, and the web, what an administrator controls, and the one requirement that stops a lot of people cold: you need a work or school Microsoft 365 account, because the full feature set is not available on a personal Outlook.com address.

Before going further, it is worth naming the requirement that causes the most confusion, because it determines whether the rest of this guide applies to you. Microsoft 365 Groups, with their shared mailbox, SharePoint files, and OneNote notebook, are a feature of a work or school account on a qualifying Microsoft 365 subscription, not of a personal, free Outlook.com or Hotmail account in the same form. Sign in with a personal account and you can still create a basic group, but it will not come with the shared resources that make a Microsoft 365 group genuinely useful. Almost everyone searching for "how to use Outlook groups" is on a work or school account, which is the scenario this article assumes throughout; the personal-account caveat is covered in its own section later.

It also helps to know which Outlook you are using, because the menus differ. There are three in practice in 2026: new Outlook for Windows (the rebuilt app, with a toggle reading "New Outlook" in the top corner), classic Outlook for Windows (the long-standing desktop application in the Microsoft 365 or Office suite), and Outlook on the web (the browser version at outlook.office.com). New Outlook and the web share nearly identical menus because new Outlook is built on the same foundation as the web app, so a single set of steps usually covers both; classic Outlook is the outlier with its own older layout. The good news is that groups appear in roughly the same place in all of them, a dedicated Groups area in the folder pane.

How do you create a group in Outlook?

Creating a group is quick once you know where the option lives. In new Outlook for Windows and on the web, groups have their own section in the left-hand folder pane, usually below your mail folders, labeled Groups, where every group you belong to is listed and where you start a new one. When you create a group you give it three things up front, a name, an email address, and a privacy setting, and you can add members and a description at the same time. Outlook then provisions the whole package: the shared inbox, calendar, files library, and notebook all come into being together.

Here is the step-by-step for new Outlook and Outlook on the web, which share the same menus. Note that if you do not see the New Group option, an administrator has likely restricted who can create groups, which we cover in the admin section.

1. 1

   Find the Groups section in the folder pane

   In new Outlook or on the web, look in the left-hand navigation for the Groups heading, usually below your mail folders, and expand it if collapsed. This area lists the groups you belong to and is where you start a new one.

2. 2

   Start a new group

   Select the option to create a new group, often a plus next to the Groups heading or a New Group command. A panel opens where you define it. In classic Outlook this lives on the Home tab of the ribbon.

3. 3

   Enter a name and email address

   Type a clear group name such as "Marketing Team." As you type, Outlook proposes a matching email address like marketingteam@yourdomain.com; adjust it if you want, since this is the address people will use to email the group.

4. 4

   Add a description and set the privacy

   Add a short description so members know the group's purpose, then choose Private or Public (covered next). Private means content is visible only to members and joining needs owner approval; Public means anyone in your organization can see it and join.

5. 5

   Add members and create

   You are prompted to add members; type the names or email addresses you want, then select Create. The group and its shared inbox, calendar, files library, and notebook are provisioned at once and the group appears in your folder pane.

A couple of choices at creation time are worth a moment's thought. The email address is effectively permanent in everyday use, the one people type to reach the team, so pick something that still makes sense in a year. The privacy setting can be changed later, but it shapes how people discover and join the group from day one. And whoever creates the group becomes its first owner, which matters because owners are the only ones who can change settings, approve join requests, add or remove members, and delete the group. Add a second owner soon after creating one, so the group is not stranded if the creator is unavailable.

In classic Outlook for Windows the experience is broadly the same but reached through the ribbon: on the Home tab there is a Groups area, and the New Group button opens a similar dialog for the name, address, description, privacy, and members. One caveat: classic Outlook has varied over the years in how fully it supports every group feature, so for the richest experience, especially around the files library and notebook, the web app and new Outlook tend to be the smoothest places to work.

How do you add and remove members of a group?

Managing who is in a group is one of the most frequent tasks once it exists. You are prompted to add members when you create a group, but you will almost always need to add more later and remove some as they move on. Membership is managed by an owner; ordinary members can see who else is in the group but cannot add or remove people. Because the email, calendar, files, and notebook all share one membership list, adding a person grants them access to everything the group owns in a single step, and removing them revokes it just as cleanly, with no separate "give them the files too" action to remember.

To manage members in new Outlook or on the web, open the group and go into its settings or member list. The wording varies slightly by version, but the path is consistent: find the group, open its settings view, and you will see the current members with controls to add and remove. Here is the typical flow.

1. 1

   Open the group in the folder pane

   In the Groups section of your folder pane, select the group you want to manage. Its shared inbox opens, and the group's name and management options appear at the top.

2. 2

   Open the group settings or member list

   Open the group's settings, often via a Group Settings command, a gear, or by selecting the member count near the group name. This reveals the list of current members and owners.

3. 3

   Add members

   Choose the option to add members, type the names or email addresses you want, and confirm. They gain access to the inbox, calendar, files, and notebook at once, and start receiving the group's mail.

4. 4

   Remove a member or change a role

   To remove someone, find them in the member list and select the remove option next to their name. To make a member an owner (or step one back down), use the role control in the same list. Removing someone revokes access to all the group's resources.

5. 5

   Confirm the changes

   Save or confirm. Membership changes usually take effect quickly, though there can be a short delay before a new member sees everything in their Outlook.

A related concept sits alongside membership and often gets muddled with it: following a group. Being a member means you belong and have access to all its resources. Following (or subscribing) is the additional choice of whether the group's conversations also land in your personal inbox. A member who follows receives its email in their own inbox as well as in the shared inbox, useful when you want to keep a close eye on the discussion. A member who does not follow still has full access but only sees conversations when they open the group. Owners influence the default for new members, and individuals can change their own follow setting at any time.

Keep the owner list small and deliberate so membership changes stay controlled, while still adding a second owner for resilience. And because removing a member instantly cuts their access to the files and notebook as well as the mail, offboarding someone from a group is a genuinely useful single action, far cleaner than chasing down each shared resource by hand.

What is the difference between a public and a private group?

The privacy setting you choose when creating a group is one of its most consequential, because it governs who can see the content and who can join. Microsoft 365 Groups come in two flavors, public and private. In a public group, the content, conversations, files, and calendar, can be seen by anybody in your organization, and anybody can join on their own without approval. In a private group, the content is visible only to members, and anyone who wants to join has to be approved by an owner. Public is open by default within the company; private is gated.

Choosing between them is really a question about the group's work. A public group suits an open, organization-wide community where the point is that anyone can find it, read along, and pitch in, an internal interest group, an announcements space, a community of practice. A private group suits a defined team or a sensitive topic where conversations and files should stay within a known membership, a project team handling confidential plans, an HR working group, a leadership discussion. Many organizations lean private by default, on the principle that it is easier to open a group up later than to claw back content that was visible to everyone.

The setting is not locked in: an owner can switch a group between public and private later, through the group's settings. That flexibility is reassuring, but treat the initial choice as the one that matters, because changing it has consequences. Making a private group public exposes its existing content to the whole organization, which may include conversations or files shared on the understanding they would stay within the group. Making a public group private narrows future access but does not retroactively un-share what people may already have seen. The table lays out the practical differences so you can match the setting to the group's purpose.

It is worth being clear that public here means public within your organization, not public to the entire internet. A public Microsoft 365 group is visible and joinable by people who already have an account in your company's tenant; it does not put your conversations on the open web. Outsiders only get involved if added as guests, and guest access is governed separately by admin-controlled policies. So the public-versus-private decision is about how open the group is to your own colleagues, not exposure to the outside world.

How do you send an email to a group and view its conversations?

Once a group exists and has members, the day-to-day reality of using it is mostly email, and emailing a group is reassuringly simple. You send a message to a group exactly as you send one to a person: put the group's email address in the To field, add a subject, type your message, and send. Every member receives it, and the message is kept in the group's shared inbox where any member can read it, now or later. You do not need to copy members individually; the single address reaches everyone and files the conversation in the shared space at once.

Reading and replying to a group's conversations happens in the shared inbox, reached by selecting the group in the Groups section of your folder pane. Opening it shows the conversations much like an inbox, threaded so you can follow a discussion, with the full history to scroll back through. This is what sets a group apart from a plain mailing list: the conversation is not delivered and gone, it lives in a shared place. A member who joins later can scroll back and read everything that came before, and anyone can search the history for a past discussion. You reply the way you reply to any email, and your reply goes back into the shared inbox and out to the members, keeping everyone on the same page.

1. 1

   Email the group like any contact

   Start a new message and type the group's email address (or name, which Outlook resolves) in the To field. Add a subject and your message, then send. Every member receives it and the message is stored in the shared inbox.

2. 2

   Open the group to read its conversations

   In the Groups section of your folder pane, select the group. Its shared inbox opens, showing the conversations threaded so you can follow each discussion, the record every member can see.

3. 3

   Reply and keep the thread together

   Open a conversation and reply as you would to any email. Your reply returns to the shared inbox and reaches the members, so the discussion stays in one place rather than fragmenting.

4. 4

   Search or scroll the history to catch up

   New to the group, or back after time away? Scroll the conversations or search to find a past discussion. Because the history lives in the shared inbox, you catch up without anyone forwarding it to you.

Members who follow the group get an extra convenience: the conversations also arrive in their personal inbox, so they can read and reply without remembering to open the group. Members who do not follow keep their personal inbox clear and visit the group to catch up. Either way the conversation is preserved in the shared inbox, so following only changes whether copies also reach the personal inbox, never whether the shared record exists. People sometimes assume they are missing messages when in fact they are simply not following the group, the messages are all there inside it.

A small but useful point about replies: by design, a reply to a group conversation goes to the group, keeping the discussion in the shared space, rather than only to the original sender. That is usually what you want for team discussion, though it means a moment's thought before a personal aside in a group thread, since it lands in the shared inbox for all members; for a side conversation, start a normal direct email instead.

How do the shared calendar, files, and notebook work?

Email is the front door of a Microsoft 365 group, but the shared resources behind it are a large part of why a group beats a simple mailing list. Every group comes with a shared calendar, a shared files library, and a shared OneNote notebook, all available to every member and governed by the same membership. You do not set them up separately or grant access one by one; they exist from the moment the group is created and a member has them automatically, one list of people, one set of shared things.

The shared calendar is for the group's events: meetings, deadlines, milestones, anything the whole team should see. When an event is posted to it, members can have it appear on their own calendars too, so a team's schedule lives in one shared place while still surfacing for each person. You reach it by opening the group and switching to its Calendar view. This is handy for project teams, where the alternative, inviting everyone individually to every event, is exactly the busywork a group removes. The calendar belongs to the group, so it persists as people come and go.

The files library is backed by SharePoint, simply where Microsoft 365 stores a group's shared documents. From inside the group you open the files area to see what the team has shared, add new files, and work on them together, with storage and versioning handled underneath. Because it is the same membership list, every member reaches the files without a separate share, and removing a member cuts off their access along with everything else. Alongside the files sits a shared OneNote notebook for the team's notes, research, and ideas, again shared automatically. Between the inbox, calendar, files, and notebook, a group gives a team a surprisingly complete shared workspace from a single creation step, which is why Microsoft positions groups as the default container for team collaboration.

Groups vs distribution list vs shared mailbox vs Teams: which should you use?

A common reason people search for Outlook groups is to figure out whether a group is even the right tool, given that Microsoft offers several overlapping ways for a team to share email and collaborate. The four compared most are the Microsoft 365 group, the distribution list, the shared mailbox, and Microsoft Teams. They overlap enough to be confusing, but each has a center of gravity. The short version: distribution lists are for one-way broadcast, shared mailboxes are for a customer-facing team inbox, groups are the all-in-one collaboration container, and Teams is for chat-first, real-time teamwork (and is itself built on a group).

A distribution list (or distribution group) is the simplest of the four. When someone emails its address, the message is forwarded to everyone on it, and that is essentially all it does, no shared inbox, no history, no calendar, no files; the mail simply fans out to individual inboxes. It is right when communication is one-way, no coordinated reply is expected, and you do not need to track who responded, think company announcements or a department newsletter. The moment you need a shared record or shared resources, it runs out of road, which is why Microsoft now nudges people toward groups for anything beyond pure broadcast.

A shared mailbox is a single address, like support@ or sales@, that several people open from inside their own Outlook, with incoming mail in one inbox everyone can see and, when configured, sent replies stored centrally. Its strength is a customer-facing team queue: a help desk or sales line where you track response times, avoid duplicate replies, and present one consistent identity outward, a model more intuitive for staffing a queue than a group's conversation view. A Microsoft 365 group, by contrast, is the all-in-one collaboration container, shared inbox plus calendar plus files plus notebook, oriented toward ongoing internal teamwork rather than fronting a support address. Microsoft Teams takes the same group foundation and adds chat-first, real-time collaboration, channels, calls, meetings, so when a team's work is conversational and immediate, Teams is the natural home, and it quietly creates a group to hold its mailbox, calendar, and files anyway. The table sets the four side by side.

A few rules of thumb cut through the overlap. If you only need to send to a list and nobody replies to a shared space, a distribution list is the lightest fit. For an external-facing queue where shared sent items, response tracking, and one outward identity matter, a shared mailbox is usually more intuitive than a group. If you want a team container, email, files, calendar, and notebook together, a Microsoft 365 group is the modern default and the foundation the others build on. And if the team's work is really chat with email as a sideline, start in Teams and let it create the group for you. These are not rigid walls: a group you create in Outlook can later gain a Teams workspace, so choosing well simply saves migrating later.

All four tools share a deeper limitation as teams grow: they were built for a single mail system and a fairly traditional shape of teamwork. A distribution list cannot tell you who is handling what. A shared mailbox blurs individual accountability by design. A group keeps a shared record but has no real notion of assigning a conversation to a person. And none stretch cleanly beyond the Microsoft world to a team that also runs a Gmail or IMAP address. That gap is where a purpose-built shared-inbox tool comes in, which we return to later.

How do you join, leave, or follow a group?

Beyond creating and managing groups, the most common everyday membership actions are joining, leaving, and changing whether you follow a group. Joining depends on privacy. To find groups you can join, browse or discover groups in your organization; when you open one you see an option to Join or to Request to Join. For a public group, selecting Join adds you straight away. For a private group, the same action sends a request to an owner, who can approve or decline it; you become a member only once approved. This is the earlier privacy distinction as an action: public groups you simply join, private groups you ask to join.

Leaving is just as direct: from within the group, open its settings and choose the option to leave, often labeled Leave Group. Once you leave, you stop receiving the group's mail and lose access to its shared inbox, calendar, files, and notebook, the mirror image of joining. One sensible safeguard: if you are the only owner of a group, you generally cannot simply leave and orphan it; you need to make someone else an owner first. This is another reason the earlier advice to add a second owner pays off, it keeps your own exit unblocked as well as protecting the group.

1. 1

   Find a group to join

   Browse or discover groups in your organization through the Groups area. Open one to see its description and members and to find the join control.

2. 2

   Join or request to join

   Select Join (or Request to Join). For a public group you are added immediately. For a private group, your request goes to an owner, who approves or declines it; you join once approved.

3. 3

   Choose whether to follow it

   Decide whether to follow (subscribe to) the group so its conversations also reach your personal inbox. Follow one whose discussion you want to track in real time; leave it unfollowed to keep your inbox quiet and read the group when you visit.

4. 4

   Leave the group when you no longer need it

   Open the group's settings and select Leave Group. You stop receiving its mail and lose access to its shared resources. If you are the only owner, make someone else an owner first.

Following is the lever people most often want and least often find. If a group is too noisy in your personal inbox, you do not have to leave it, just stop following it, and its conversations stay in the group while you keep full access. Conversely, if you keep missing a discussion because you forget to open the group, follow it so the messages come to you. The right move when a group feels wrong in your inbox is almost never to leave, it is to adjust whether you follow it.

How do groups differ in new Outlook, classic Outlook, and the web?

Because there are three Outlooks in active use, it helps to know where groups sit and how the experience differs, even though the core concept is identical everywhere. In new Outlook for Windows and on the web, groups live in a dedicated Groups section in the left-hand folder pane, and because new Outlook is built on the same foundation as the web, the two behave almost identically. For most people on a modern Microsoft 365 setup, new Outlook or the web is where group features are the most complete and consistent, so if you have the choice, those are the easiest places to work.

Classic Outlook for Windows also supports groups, reached through a Groups area on the Home tab and listed under a Groups heading in the folder pane, but its support has historically lagged in places, particularly the richer parts like the files library and notebook. The fundamentals, creating a group, emailing it, reading conversations, managing members, are all there, but if a feature seems missing or behaves oddly in classic Outlook, the standard advice is to do that task on the web, where the full experience is reliably available. Classic Outlook is gradually being superseded by new Outlook, so this gap closes over time, but in 2026 it is still worth reaching for the web app when a group feature is not cooperating.

There is also the Outlook mobile app on iOS and Android, which supports groups too: you can browse and open your groups, read and reply to conversations, and access group events from your phone. Some management tasks are easier on a larger screen, but for the everyday act of reading and replying, mobile does the job. Across all of these, the same underlying Microsoft 365 group is what you are touching, so a change made on the web shows up on mobile and in new Outlook, because there is only ever one group behind the different windows onto it.

What does an administrator control, and what does Microsoft 365 require?

Groups feel like a self-service feature, and for many people they are, but an administrator sits behind the scenes with meaningful control, which explains a lot of the "why can't I do this" moments. The most consequential setting is who is allowed to create groups. Many organizations let any user create one, but an admin can restrict creation to a specific set of people, so if you cannot find a New Group option, the likeliest explanation is a policy rather than a bug: group creation has been limited, and you would need to ask your administrator to create the group or grant you the ability. Admins also control naming policies, expiration policies that clean up unused groups, and whether external guests can be added at all.

The harder requirement, the one that stops people before any setting matters, is licensing and account type. Full Microsoft 365 Groups depend on the services that back them: the shared mailbox needs Exchange Online, and the files library needs SharePoint Online. Any subscription that includes both supports groups, which covers the common business and enterprise plans, but a plan without those services, or a personal consumer account, does not provide the full experience. This is a direct consequence of groups being assembled from Exchange and SharePoint, not an arbitrary gate: on a qualifying plan, groups simply work; on a personal Outlook.com account, the full feature set is not there to switch on.

1. 1

   Confirm the account and plan

   Check that you are on a work or school account with a Microsoft 365 plan that includes Exchange Online and SharePoint Online. Common business and enterprise plans qualify; personal consumer accounts do not provide the full experience.

2. 2

   Check whether group creation is allowed

   If you cannot see a New Group option, your administrator may have restricted who can create groups. This is a deliberate policy, not a fault. Ask your admin to create the group or grant you the ability.

3. 3

   Be aware of naming and expiration policies

   Admins can enforce naming conventions and expiration policies that retire unused groups. If a name is rejected or an old group disappears, an organizational policy is usually the reason.

4. 4

   Understand guest access

   Whether outsiders can be added to a group as guests is controlled by an administrator. If you need to include an external partner and cannot, guest access may be turned off or limited by policy.

5. 5

   Escalate to the admin when blocked

   For anything you cannot do yourself, creating a group when creation is restricted, adding a guest, changing a policy, the route is your Microsoft 365 administrator. Groups are centrally governable, so admin involvement is normal.

For administrators, the guidance is to manage groups with a light but deliberate hand. Letting users create groups freely encourages adoption, but pairing that with naming and expiration policies keeps the directory from filling up with abandoned or confusingly named groups. Guest access is a security decision rather than a convenience toggle, since adding an external guest grants access to the group's conversations and files, so it deserves a considered policy. And because every group is backed by Exchange and SharePoint, deleting one removes its mailbox and files together, clean but irreversible after the retention window, so make sure owners understand what deletion entails before they reach for it.

Can you use Outlook groups with a personal account, and what else goes wrong?

The single biggest source of disappointment with Outlook groups is discovering, after trying to create one, that your account does not support them properly. Signed in with a personal Outlook.com, Hotmail, or similar consumer address, you can create a basic group, but it will not include the shared OneNote, SharePoint, or Planner resources that make a Microsoft 365 group worth having. The rich collaboration container is a work-or-school-account feature; no setting within a personal account turns it on, because the full feature set is a property of a qualifying organizational subscription. If groups matter to you, the answer on a personal account is a work or school account on the right plan, not a different button to press.

Beyond the account requirement, a handful of issues cause most of the trouble people hit. Not seeing a Groups section at all usually means one of three things: a personal account, a plan that lacks the necessary Exchange and SharePoint services, or an admin who has restricted group creation. Not being able to create a group specifically, when groups otherwise appear, points squarely at the admin restriction. Thinking you are missing the group's mail is usually just that you are not following it, the messages are all in the shared inbox. And being unable to add an external person is typically a guest-access policy set by an admin. The table maps these to their fixes.

A last category worth flagging is the confusion between a Microsoft 365 group and the older "contact group" (once called a personal distribution list) that you build in Outlook from a set of contacts. A contact group is just a saved bundle of addresses that lets you type one name to email several people; it is private to you, with no shared inbox, calendar, files, or membership anyone else can see. It is useful for emailing the same handful of people repeatedly, but it is not a Microsoft 365 group. If you searched for "Outlook groups" hoping for a shared team workspace and ended up with a contact group, that is why it felt thin, you built the address-book tool, not the collaboration container.

How does AI Emaily give teams a shared inbox and delegation across every provider?

Outlook groups solve a real problem, and for a team that lives entirely inside Microsoft 365 they are a capable way to share email, files, a calendar, and a notebook from one membership list. But this guide has surfaced the seams, and they are the same ones every Microsoft sharing tool shares. A group keeps a shared conversation but has no real concept of assigning a thread to a person, so on a busy team two people can still answer the same message. The whole apparatus assumes one mail system, so a team that also runs a Gmail or IMAP address needs an entirely separate setup. And the richest features depend on the right plan, account type, and admin policies, a lot of plumbing for what teams increasingly just want: a shared inbox where it is clear who is handling what.

AI Emaily is an AI-native email client built around the way teams actually share mail now. Instead of a shared conversation with no ownership, it gives you a true shared inbox with human-or-agent delegation: assign any conversation to a specific teammate, so there is clear ownership and two people do not reply to the same message, or hand it to an AI agent that can triage, draft a reply, sort, and follow up. You keep humans for the judgment calls and let the agent absorb the repetitive volume, with a full record of who, or what, did each thing, the accountability a group's shared inbox cannot give you on its own.

Crucially, it works across every provider, not just Outlook. The same shared inbox and delegation sit on top of Outlook, Gmail, and other accounts together, so a team handling email across more than one mail system runs it all in one place rather than a separate group, distribution list, or shared mailbox per provider. There is no plan-and-policy gate to clear and no requirement that everything live in one company's mail system. The agent runs in Manual, Copilot, or Autopilot, always with one-tap undo and an audit trail, so you decide how much it does on its own, with the shared context of the whole conversation behind every action.

AI Emaily starts free at $0, with Pro at $17.99 a month and Team at $22.99 per seat a month, both billed annually, so a small team can try a real shared inbox without committing budget up front. If the group setup in this article, the plan requirements, the admin policies, the lack of per-conversation ownership, the way none of it crosses to another provider, is more friction than your team should spend time on, it is worth seeing how much disappears when sharing and delegation are built into the client itself.

Putting it all together

Using Outlook groups well comes down to understanding what a group actually is, a Microsoft 365 collaboration container that bundles a shared inbox, calendar, files library, and notebook under one name, one address, and one membership list, and matching how you use it to that design. You create a group from the Groups area in the folder pane, choosing a name, an address, and a public-or-private setting, and add a second owner so management is never stranded. You manage members from the group's settings, where adding or removing someone grants or revokes access to everything at once. You email the group like any contact, and its conversations live in a shared inbox any member can scroll back through, with following controlling whether copies also reach your inbox.

The choices that matter most are the ones easiest to skip past: public versus private, which governs who can see and join; member versus owner, which governs who can manage it; and following versus not, which governs your own inbox noise. Keep clear, too, on which tool fits the job, a distribution list for one-way broadcast, a shared mailbox for a customer-facing queue, a group for ongoing internal teamwork, and Teams for chat-first work, and remember the work-or-school-account requirement that underpins the whole feature set.

And if the group machinery starts to feel like more administration than your team should maintain, especially across more than one email provider, that is the signal to look at a tool where a shared inbox and delegation are native rather than configured. AI Emaily handles team mail with a real shared inbox, human-or-agent delegation, clear per-conversation ownership, and shared context across every provider, starting free at app.aiemaily.com/signup. Either way, you now know how to create, manage, email, and use an Outlook group in whichever Outlook you are running.
