Apple Mail Problem


My wife's email account is playing up. She deletes emails from her inbox and then empties the trash. Lo and behold half and hour later the emails have returned into her inbox.

She simply can't delete any of the thousands of emails in her inbox. Any help with this matter would be gratefully received.
You have given absolutely no information about your wife's email account. It sounds like she has a POP account. It also sounds like Mail on her account is not configured to automatically delete messages from the server.
Apologies. She has an Apple email account, so I assume that's an IMAP account. Also looked at her preferences and 'store deleted emails on server' was checked. Now I have unchecked it. Do you think that was the problem?
Yep, that was the problem. The Mail app looks at the server and sees emails that it does not have and downloads them again.
