I have been using thunderbird very actively and happily for years now. However, it seems I have hit a brick wall.
I have setup a new computer using CentOS8 and installed the stock thunderbird version 68.9.0 (64-bit) I have setup two of my mail accounts successfully already. However, the third one, my work email account (I work at CERN), is giving me trouble.
When I enter my name, address and password into the wizard, it tries to search for settings. However, instead of the correct addresses of the IMAP and SMTP servers (imap.cern.ch and smtp.cern.ch), it suggests "outlook.office365.com", probably as a result of the fact that it also searches for Microsoft Exhange servers and CERN used to have some of those in the past (they are being phased out now).
Since I know the credentials anyway, I can enter the IMAP and SMTP server addresses by hand, alongside the authentication methods and ports (SSL for IMAP, STARTTLS for SMTP). Now I click "Re-test", but I just get "Thunderbird failed to find the settings for your email account". I know for a fact that the credentials are correct, as I can sync just fine from my private laptop (thunderbird on archlinux) and my phone (gmail on android). This leads me to believe that the problem is indeed on my side, and not a mere server configuration issue. It is possible that the problem does not come from thunderbird, but from some underlying piece of software (e.g. openssl, my system security settings, or perhaps even the wired network I'm connected to on this computer,) - but the thunderbird output is less than helpful.
What can I do to get a more precise description from thunderbird as to why the setup of my email account failed and what I can to do fix it?
