All 4 of my Thunderbird email accounts have suddenly ceased to retrieve emails resulting in an error message stating that either my username or password are incorrect. However, I am able to logon and see all of my emails when I open a browser to outlook.office365.com so I know all my usernames and passwords are correct. I have not changed any of my account settings in Thunderbird. Any ideas how I can fix this?

Problem solved! I had to simply change my authentication method to OAuth2

Weirdly, I can send mail using the smtp.office365.com server but retrieval with the POP server setting of outlook.office365.com simply does not work.

What authorization method are you using for your incoming account.

SSL/TLS method with normal password authentication

My provider (godaddy.com) says, "Microsoft deprecates basic authentication (POP and IMAP)."

They now want an MFA sign in that does not seem possible with Thunderbird?
