Thank you for coming back to me. Hopefully I am on the right site now. A few days back my laptop computer was compromised and I was instructed by my bank to a factory restart which meant I lost all of my apps etc. I have restored most of my previous apps but have been unable to restore my Thunderbird Email system I have been using for over four years and find it great but I have lost access to all my contact addresses and saved emails. I have tried to restore the system and have reset my password but when I get to the point of completion and click "done" I get the message "unable to log in at the server. Probably wrong configuration, User name or Password. I have been very happy with Thunderbird for many years now and hopefully things can be retreived. I am using Microsoft Mail at the moment so I can send and receive emails. Thank you, Malcolm Gresswell
