1 flag still showing up in the flag folder
For months now I have a flag showing up in the 'flagged' mailbox but no message there. I've searched for flagged message and there are none, I have rebuild mailboxes and still it remains. I have given in and would love a solution. And yes I have restarted my machine as well. For this reason I avoid using flags at all, but when I do, the number increases and the message moves to the flagged folder and they show up there, I unflag them, they get removed and that (1) still shows up but nothing there.
Any solutions? I'm grateful!
