setting up an email account that was already set up
All the emails in one of my Thunderbird (TB)accounts deleted a total of over a hundred emails over time when Thunderbird (TB) closed. I still have 5 other TB accounts that are open. The other accounts do not delete the emails as my main account (MMA) does. The deleted emails did not go into another folder such as Deleted or Junk. The top of the MMA display states 100 plus emails are in MMA, but I cannot find or answer them. Question 1: Where are the emails and how can I recover them?
Secondly, now a new problem. A tech deleted MMA and tried to reinstall the MMA to recover the 100+ emails. He could not reinstate the MMA, nor can I. When we tried to reinstate MMA, it states “Unable to log in at server. Probably wrong configuration, username or password.” It will not accept the only 2 passwords I have used. How can I change the password and reinstate MMA?
