Thunderbird-Hilfeforum

Hi; I noticed today that many years of archived emails have disappeared in all but 1 account(yahoo). The only years still there are 2020 and 2021 in 5 different accounts. 5 yrs in 1 account and complete 24 yrs in yahoo account. These accounts archives that disappeared are not stored on the mail server but locally. What has happened??? Can I get them back? How do I stop this from happening?

Today I went to close Thunderbird using File>Exit. It does not close, and I see the the "Emptied Trash" message. If I go to click on "File" again there is often no dropdown. If I go to close it using the "X" it closes. When I try start it again it will not start. I have to go to the task manager where I find instances of it running, and close them...then it will start. When it is started, I can close it using the X and it starts normally. All extensions are disabled.

Very occasionally Thunderbird will close using File>Exit but will not start normally.

Any ideas?
