Comment 86 for bug 2004480

It worked for 19 years on my own POP3 server, then 10 years on outlook hosted on Rackspace, then after the Rackspace meltdown in November, Thunderbird worked for about 2 months on outlook.office.365.com. Then on about January 23rd, (we had not yet upgraded to 102.7.0), both my Thunderbird and my Wife's started looping on asking for the password over and over again. I tried many different things (ports, protocols, etc.) and never got a download again, the IT guy at my corporate account said that he could see me signing in, but I never got a download. We can get our mail with Mac Mail and iOS Mail, but those are IMAP. I have a couple of decades of thunderbird emails that I would like access to again (I really want to get thunderbird going again).

I lost all my profiles, in the "trying things" stage, so yes, I created a new profile on 102.7.1 and used both autodetect, and ports and protocols experiments. Still looping.

I just downloaded Thunderbird 110.0b3.pkg, I'll give it a try.
