At a new company I started, they use Office 365 as their mail server (using their domain), together with two factor authentication. However, I can't seem to configure my mail account in Thunderbird. According to some posts, they have been successful, but I always get an "authentication failed when connecting to outlook.office365.com" error.
I have attached a screen capture of my configuration. I use the imap server outlook.office365.com at port 993 with SSL/TLS and OAuth2 authentication, and smtp server smtp.office365.com at port 587 with STARTLS and OAuth2 authentication. I use my email address as the username in both cases.
When I click on "Test" it says that it has found the right parameters have been found, but when I click on "Done", it just fails.
At some point, a windows with microsoft's two factor authentication appeared, where I could enter my email and password and log in, but Thunderbird still complained that it cannot authenticate to the server.
I am using Ubuntu 20.04 with Thunderbird 78.5.1 (64 bits) (I also tried with a nightly build, with the same result).
Any ideas? Is it currently possible to use O365/Exchange mail accounts in Thunderbird?
