2 possibly related issues. Environment Win10 latest Thunderbird version eMail server is google I was moving a large number of folders from a POP account to a new IMAP account. Something bad happened and Thunderbird died without an error message. When I restarted I found a lot of the POP folders had not transferred and there is a lock symbol on the POP account and I can not open it to show what is in it. Question 1: what does the lock symbol designate and how do I unlock the account. Question 2: are the missing folders gone? I realize that I probably need to solve #1 first. -- bill
