Comment 89 for bug 2004480

(In reply to steve from comment #83)
> 110.0b3.pkg creates a executable called "Thunderbird Daily.app". Starting it up takes you to the Startup screen, where the same problem occurred. I think it said "You are about to override how Daily identifies this site."

I don't think you're experiencing anything related to this bug at all, sorry. If you had problems before upgrading to 102.7.0 it's not possible.

Also, there is nothing wrong with the office365.com SSL certificate, the fact that you're seeing these certificate issues implies you have some sort of antivirus installed that MITMs certificates or something like that, [as described in this support request](https://support.mozilla.org/en-US/questions/1311167).

You should never, ever have to do a certificate override on a mail server and it's not related to oAuth.
