Deleted email re-appears in inbox after it has been deleted in Mail app After upgrading to Catalina on my MacBook Pro, I noticed that deleted emails re-appear in my in box after a few minutes after the deletion. The only way I can really delete them is by using my iPad or my phone to delete them. At least they don't re-appear if I use any of those devices.

Is this an introduced bug in the Catalina version of Mac mail? Is anyone else experiencing the same issue?
I removed [the google account] and added it again and the issue went away. 


System Preferences → Internet Accounts, remove the troubling IMAP account and add it back. For a less drastic measure, uncheck the Mail checkbox and tick it again.
