I have a client who's Thunderbird email suddenly disappeared, as when they logged in one morning, Thunderbird asked them to create a new account. I would like to be prepared in finding a solution to their problem, and the only other listing i saw was 5 years ago, and I;m certain on another version.
Below is a listing of answers to questions i asked them to detail:
1) Thunderbird Version 126.96.36.199 pr (20100408)
2) The first instance of missing email was after a reboot. When opening Thunderbird, the Wizard came up to set up and new account/profile. After that was done, all the old folders and emails did not appear (but those on the server were downloaded).
3)Used the ImportExportTools extension to try to reimport the folders and mail. However, this did not work. The extension, which is an addon to Thunderbird, can be found here:
The client also followed the instructions under Is your profile intact? found here: http://kb.mozillazine.org/Recovering_a_profile_that_suddenly_disappeared
Apparently, Thunderbird does seem to have a problem with disappearing profiles.
Any additional ideas to locate and recover the lost email will provide a great assist.
