How to Export Yahoo Mail to PST, Gmail or Another Provider

How to export Yahoo Mail#

The short answer to how to export Yahoo Mail: use IMAP, not Yahoo's download button. Create a Yahoo app password, connect Yahoo to a desktop mail client, and let it download every folder. From there you either drag folders into a new provider's account, or save them to a file such as an Outlook PST. Messages keep their folder structure, read state and dates.

Yahoo's own data download is a privacy export, not a migration tool. It arrives as JSON, can take up to 30 days to become available, and is not something you can import into a new mailbox. It is a useful archive but a bad way to move.

This guide covers what moves and what does not, the order to do it in, how to export Yahoo Mail to PST or Outlook, and the Yahoo-specific trap that catches people months later.

Which Yahoo export do you need?#

There are only a few mechanisms, and the differences decide how much you lose. Pick the row that matches the result you want, then jump to that section.

Before you start: checklist#

Do this before copying a single message. Each item takes a few minutes now and is painful to reconstruct later.

• Create the destination account first, and verify you can send from it.
• Generate a Yahoo app password. Yahoo says third-party mail apps that do not use its own sign-in page need one; your normal password will be rejected.
• Check free disk space. Years of attachments can add up to tens of gigabytes, and the copy lands on your machine first.
• Export Yahoo Contacts to CSV before touching the mail.
• Export your Yahoo Calendar if you use it, using the export option in Yahoo Calendar. Its menu labels change, so check Yahoo's help if you cannot find it.
• Screenshot your Yahoo filters, signature and vacation-reply text.
• List every service that emails your Yahoo address: bank, tax, utilities, domain registrar, two-factor recovery. This list is the real migration, and it's longer than you think.
• Pick a date you can leave both mailboxes running for at least a month afterwards.

How to export Yahoo Mail over IMAP, step by step#

Thunderbird is the usual tool here: free, cross-platform, and happy to hold two IMAP accounts side by side. Apple Mail and Outlook do the same job with a near-identical sequence.

1. 1

   Generate a Yahoo app password

   Sign in to Yahoo Account Security, open the External connections section and choose Create app password. Copy it somewhere temporary.

2. 2

   Add Yahoo to the desktop client with the export server

   Incoming: export.imap.mail.yahoo.com, port 993, SSL/TLS. Yahoo's guide to downloading your email with IMAP uses this host, and its everyday IMAP page points to it for anyone not seeing all their old messages. Outgoing: smtp.mail.yahoo.com, port 465 or 587, authentication required. Username is your full Yahoo address; password is the app password. For ordinary day-to-day use afterwards, imap.mail.yahoo.com is the regular server.

3. 3

   Tell the client to download full messages

   Yahoo's guide says to set your app to download the full contents of each email, not just previews, and to answer yes if it asks whether to keep mail on the server, otherwise messages can be removed from your Yahoo account after download. Yahoo also warns that folders with around 100 thousand or more messages may not download completely, so split very large folders first.

4. 4

   Add the destination account in the same client

   Use the new provider's IMAP settings. Both accounts now sit in the same folder tree, which is what turns the copy into a drag rather than an export-import.

5. 5

   Force a full download of the Yahoo side

   In Thunderbird, right-click the Yahoo account, choose Subscribe, and tick every folder, then open each one once so the client fetches the headers. Nothing copies that it hasn't seen. Yahoo says accounts with a lot of content can take several days or longer to download.

6. 6

   Create the destination folders, then copy in batches

   Make an empty folder on the new account, select a few hundred messages in the matching Yahoo folder, and drag them across. Small batches are slower to start but far easier to resume than one huge drag.

7. 7

   Work oldest to newest, one folder at a time

   Start with archives, finish with the inbox. If the copy stalls, you know exactly where, and today's mail is still where you left it.

8. 8

   Verify by count, not by feel

   Compare each folder's message count on both sides, then open the oldest and newest message in a few folders and confirm attachments open.

9. 9

   Import contacts on the destination

   Export Contacts from Yahoo as CSV, then import that file into the new address book. Yahoo's help describes an Export (CSV) option under the contacts menu, though labels vary by version. Expect to fix a handful of field mappings by hand.

Export Yahoo Mail to a PST file or Outlook#

People who search for how to export Yahoo Mail to PST usually want one of two things: a backup file Outlook can open, or all their Yahoo mail inside Outlook. Both start the same way, with Yahoo added to Outlook over IMAP. The free manual route uses classic Outlook for Windows. Third-party converter tools exist too, but they also need your app password, so the manual route costs nothing and keeps credentials on your machine.

1. 1

   Create a Yahoo app password

   Same as the IMAP steps above: Yahoo Account Security, External connections, Create app password.

2. 2

   Add Yahoo to classic Outlook over IMAP

   Add the account in Outlook. If it does not detect the settings, enter them manually: incoming export.imap.mail.yahoo.com (or imap.mail.yahoo.com for ordinary use), port 993 with SSL, outgoing smtp.mail.yahoo.com on 465 or 587, and the app password. Setup screens differ a little between Outlook versions.

3. 3

   Wait for the folders to sync

   Let Outlook finish downloading every folder you want in the file. A mailbox that is still syncing will give you an incomplete PST.

4. 4

   Open the export wizard

   In classic Outlook, choose File, then Open & Export, then Import/Export.

5. 5

   Export to an Outlook Data File

   Choose Export to a file, then Outlook Data File (.pst), and click Next.

6. 6

   Pick the Yahoo account and save

   Select the Yahoo mailbox at the top of the list and keep Include subfolders ticked to take everything. Browse to a save location, name the file, and finish. Microsoft's guide says Outlook starts the export straight away unless you create a new file or set a password.

Export Yahoo Mail to a file you can keep (MBOX or EML)#

If you want standard message files rather than a PST, connect Yahoo in Thunderbird as above and let it download every folder. Thunderbird keeps mail in MBOX internally, and a third-party add-on such as ImportExportTools NG can export folders as MBOX or EML. It is not from Yahoo or Mozilla, so check that your version of Thunderbird supports it. Our guide to export and import email between clients covers the add-on in more detail.

Do not expect AI Emaily to import these files: it does not read MBOX or EML. Keep them as an archive, or load them into the new provider through its own import route.

What actually moves, and what doesn't#

Almost everyone underestimates this, then discovers the gap after they've stopped checking Yahoo. Mail moves well; everything attached to the mailbox rather than inside it moves badly or not at all.

IMAP, as defined in RFC 9051, is a protocol for synchronising messages and folders, full stop. It has no concept of filters, signatures, contacts or calendars, so none of those travel with a copy. For Yahoo's own server settings, see our Yahoo Mail IMAP settings guide.

What about Yahoo's own data download?#

Yahoo does offer an export. Under Manage Your Information in your privacy controls, Download My Data lets you select products and request a download; Yahoo emails you when it's ready.

Two things make it unsuitable as a migration route. Yahoo's help page says it can take up to 30 days to become available and stays downloadable for only 30 days after that. The data arrives as JSON, which Yahoo says you can open in a plain text editor.

JSON is not MBOX and not EML, and no mail client imports it as mail. Request it for a personal record of what Yahoo held, and treat it as a filing-cabinet copy alongside your migration, never as the migration itself.

What breaks on the day, and what to do about it#

None of these are catastrophic on their own, but all of them are annoying to discover a week after you've told people your new address.

Rollback plan and overlap period#

An IMAP copy is not a move, and that is the whole safety story. The Yahoo originals sit untouched on Yahoo's servers while you copy. So rollback is mostly about not destroying the source: don't delete anything from Yahoo during the copy, and avoid any tool that offers to move mail rather than copy it. If a drag between accounts behaves like a move, hold the modifier key that forces a copy and verify the Yahoo folder count is unchanged afterwards.

If the destination turns out wrong for you, just keep using Yahoo and redo the copy into a different provider. The one irreversible action is closing the Yahoo account. Yahoo says you can recover a closed account by signing in within 30 days in most countries and regions, 90 days in Australia and New Zealand, and 180 days in Brazil, Hong Kong, India and Taiwan.

The goal during the move is that no message is ever reachable only in a mailbox you've stopped opening. Yahoo offers automatic forwarding with Yahoo Mail Plus, and its help page notes it is not available in all locales, so the classic forward-everything plan either costs money or isn't available depending on where you live.

The free alternative is to pull rather than push: leave Yahoo connected over IMAP in whichever app you now live in, alongside the new account. New Yahoo mail keeps arriving in front of you, you reply from the new address, and the mailbox stays active while you work through your list of services. Update senders in priority order: anything that can lock you out first (bank, domain registrar, two-factor recovery), then billing, then people. When the copy is finished, leave the accounts in your desktop client; it now holds a complete local copy of everything you moved, the cheapest possible backup while you're still finding out what you forgot.

Should you delete the Yahoo account afterwards?#

Usually not, and certainly not in the first year. A live Yahoo address you check occasionally is a cheap safety net for every account you forgot to update; a deleted one turns those into silent failures.

But leaving it alone isn't the same as leaving it running. Yahoo's inactive mailbox policy says a mailbox becomes inactive after 12 months without access; it stops receiving new mail and its contents are permanently removed. Yahoo sends reminders 90, 60 and 30 days before deletion. Signing in again restores access to the mailbox but not the deleted emails, folders, contacts or settings.

The same help page says that if you do not sign in to your Yahoo account for a further 6 months (18 months in total), the account is scheduled for deactivation and deletion. So the honest options are: open the mailbox once or twice a year on purpose, or close it deliberately once your update list is finished. Just don't drift into deletion by accident and lose the safety net.

Where AI Emaily fits#

We build AI Emaily, so treat this as the interested part of the page. It is not a migration tool: it won't copy your Yahoo archive anywhere, and the IMAP drag above is still the right way to move the mail.

What it does cover is the overlap period. AI Emaily connects Yahoo over IMAP alongside Gmail, Outlook or any other account in one inbox, so watching what still arrives at the old address doesn't mean living in two apps. Sending stays approval-first, with an audit trail and undo. It has a 7-day free trial on Pro and Autopilot; there is no free plan.
