How to Restore POP3 Mail to Server
A common mistake many users who keep copies of their email in their POP3 mailbox make when setting up a new email account is forgetting to change the setting to leave mail on the server, so Outlook downloads and deletes it from the server.
If this happens to you, you can restore the deleted mail to the server only if you have IMAP access to the server.
- Create an IMAP account in your profile.
- MAP accounts add a second *.pst to the profile
- Make sure you set the account to leave mail on the server in the account's More Settings. Advanced dialog.
- Drag the messages from the main Inbox to the IMAP folder's Inbox.
- The messages will be synced with the mailbox on the server.
If this happens with an Exchange server account, set the Exchange account as the default delivery location and drag any mail that does not resync with the Exchange mailbox back to the mailbox.
