After closing Thunderbird normally and relaunching the app, all e-mails older than 2 days in my main inbox were lost. Why?

After closing Thunderbird normally, doing monthly Windows patching and relaunching the app, all e-mails older than 2 days in my main inbox were lost. I am assuming that somehow this folder became corrupted. But, there were no app crashes, no errors, nothing to indicate a pending problem. Is there any way to recover?

Thunderbird manages 7 imap/pop e-mail accounts for me. None of my other folders/accounts appear to have been effected; just one inbox.

This is the third or fourth time that this has happened in the past 2-3 years. Applications that randomly loose large amounts of data are worse than useless.

Thank you for the quick reply, but... That knowledge article was only of limited help.

Something is definitely confused as I have both pop-gmail.com and pop-gmail-1.com type folders that have update dates of today. I went to find e-mails that I could import back into my inbox and nothing. Both inboxes are tiny. That KB article doesn't say how to recover when you have multiple folder sets.

I did look one new place; the archive folders. I found some old e-mails from last year that I didn't know had been archived (I don't ever do my own archiving). I found 2 e-mails from this year that I'd never seen. But I know that I probably had at least 2 dozen e-mails from 2016 that are gone.
