I had years of emails from an old hotmail email address in Thunderbird.
I'd changed the password and lost it, so for 2 yrs it didn't update in Thunderbird.
I found the password and logged in via web browser, which basically reactivated the email - apparently Microsoft purged everything since it was inactive >1 yr.
Which would be fine, it's a tertiary email, but when I opened Thunderbird and put in the new password, it synced with the server, and all the emails that were saved disappeared.
Is there any way to recover them? I tried to read how to find the files, but can't locate them.
