I can see in the Activity Manager each folder has a deleted line one by one, starting this morning when I started Thunderbird. Yesterday Thunderbird would not send, would not receive mail - nothing. Just kept asking for login, then timing out - all day. This was for two accounts. Today one of the accounts seems to be working, but the other one is the one which had all of the folders deleted one by one. I'm afraid to do anything. These are super important files - work, legal, lots and lots of important emails. PLease help
