Apple Mail Error "message --- could not be moved to mailbox "AOL"
(MacBook Pro, Big Sur 11.6.7) I cannot read, write, delete, move, etc., emails without getting several Apple Mail error messages saying the " The message - - - could not be moved to mailbox AOL" even when I'm not attempting to move one. The error description and explanation varies - see a couple of attached examples. I have deleted the AOL account, rebuilt mailboxes, checked and unchecked various Mail preferences but nothing works. I have to force quit Mail and reopen it to do anything. It works for a while but the problem returns. It's beyond annoying. Can anyone offer a fix? Thanks! Rod
