Quick answer
- Small mailbox, free: add both accounts to one mail program over IMAP, then copy folders from your old account to your new one.
- New mail only: Yahoo forwarding sends copies of incoming messages, so it does not move old emails.
- Large mailbox or new service: software moves all folders to Gmail, Office 365, AOL, iCloud or any IMAP account in one run.
You want to transfer emails from Yahoo to another account, either a second Yahoo address or a new service. Yahoo Mail has no move all button, and forwarding sends only new mail. Below are three ways to transfer emails from Yahoo to another account, Yahoo settings you need and fixes when you cannot transfer Yahoo emails to another account.
Can Yahoo forward emails to another account?
Yes, but forwarding does not transfer emails from Yahoo to another account. Yahoo's help says forwarding sends a copy of incoming messages and needs Yahoo Mail Plus. It names no step to transfer Yahoo emails to another account from your Inbox history, so old mail stays where it is.
- Open your settings gear in Yahoo Mail, then select More Settings.
- Select Mailboxes, then select your primary mailbox.
- Under Forwarding, enter your new address in Forwarding Address and select Verify.
- Sign in to your new address and follow Yahoo's verification message.
Yahoo says these steps cover its older desktop layout, and some locales do not offer that option. Check Yahoo's automatic forwarding page for your layout. Forwarding helps after you transfer emails from Yahoo to another account, since new mail still reaches you.
How to transfer emails from Yahoo to another account with a mail program?
Add both accounts to one mail program over IMAP, then copy folders across. It lets you transfer emails from Yahoo to another account for free when a mailbox is small. Thunderbird does it.
- Create an app password for every Yahoo account in Yahoo Account Security. Copy every code.
- To transfer emails from Yahoo to another account, add your old Yahoo account to Thunderbird over IMAP.

- Let your old account finish syncing. Open large folders once so full messages download.
- In your new account create a folder to hold your old mail.
- Select messages in your old folder, then drag them onto your new folder. Use copy, not move, to keep originals.

A Mozilla Support top contributor advised copying instead of moving, after you confirm full messages downloaded. An eM Client forum helper said folder names do not need to match and uploads take time, so watch Show Operations in eM Client. Menu names differ by version, so test one small folder first. IMAP mirrors deletions, so a message deleted in your mail program is deleted on Yahoo too. Ask Leo makes that point about Yahoo sync.
