I have been using Thunderbird email program for over ten years, it is set up to download my messages for an AT&T/Yahoo email address.
The SMTP/POP settings have not been changed in many years.
Today I was working normally, when suddenly there are only 11 messages in my Inbox, instead of thousands.
I have no idea how this happened, and now I am freaked out because I have no idea how to recover.
If I click on Properties for Inbox, and hit the Repair button, nothing happens.
The many other TB folders seem to be OK, I think that only the inbox is damaged
Any suggestion on how to proceed will be much appreciated.
TB version 91.5.1 on a Windows 10 version 20H2 laptop.
My last offline backup is 2 weeks old.
If I use that, which file or folder should I restore?
I wonder if I can tell TB to re-sync with the AT&T server and re-create my inbox that way?
Thank you!
