Steps to reproduce

Sadly, I don’t know. My company has 2FA enabled but that wasn’t an issue until now. I’ve heard that M$ changed something regarding “old login methods” but I haven’t found anything regarding this yet.

I ain’t got no admin privileges for MS365 so I cannot check the settings there atm.

To help resolving your issue, enable debug logging (TbSync Account Manager -> Help) and send me the debug.log via e-mail (use the title of your issue as subject of the email).
