Message :- Current operation on "Sent" did not suceed - Mail Server responded unavailable
I've had problems with Yahoo mail, my "Sent" folder was deleted. They restored this, but now in Thunderbird I get this message:- Current operation on "Sent" did not succeed, The mail Server responded unavailable. But I can send mails, it's just annoying. So how do I stop the message?

Still hoping for a response!
Please, somebody with vast experience must be able to give a clue on what is causing this!
