Hi Razmee....thanks for enquiring.

I run macOS version 26.6.2 (25G83) - Tahoe on MacBook Air M3 2024.

I noticed the issue when I started setting up some rules. I created some folders and defined the rules. But then I started received alerts like this one:

The message "XXXXXXXX" could not be moved to the mailbox "Job Alerts"

Mail was unable to open this mailbox on the server "p37-imap.mail.me.com".

The server returned the error:

Mailbox does not exist.

Alerts were popping up every time a new email could not be moved... I've disabled the rules. Then I tried to move the emails from Inbox to the folder(s) manually. one-by-one works but if I select a few, they don't move...

I've checked the accounts settings (IMAP...).

Ultimately I would like to have rules operating without triggering warnings.

let me know if you have solutions to fix it. Thanks in advance.

Why not?

What device are you trying to do this on?

What error message do you get?
