the message could not be moved to the mailbox trash - Exchange Account
Not sure if it has anything to do with the update.
Mail shows 1 unread message all the time, I've read it, still shows unread. I try to delete it and get the error "the message could not be moved to the mailbox trash", same error if I try to move it to the trash folder.
Message has been long deleted from my actual INBOX via Outlook weeks ago.
I've seen the suggestions to touch the trash settings under MAIL > Advanced, but there is no such option for Exchange accounts.
