I have Thunderbird 91.11.0, and it suddenly stopped having a connection to my outlook.office365.com email account. Thurderbird won't accept my password, but the account works as an https://outlook.office.com/ browser version in the same computer and other computers. I have not changed Thunderbird in any way, it was just unused for a few hours.

Using Thunderbird version: 102.4.2 (64-bittinen) and managed to get info fron DNA operator. GO to Tilien asetukset (Account settings) and open Palvelimen asetukset (Server settings). Under headline Turva-asetukset (Security settings) click Todennustapa (Authentication) and select OAuth2 This worked at least for me.

Update: I did get the receiving of e-mail to work, but it seems that this doesn't help with sending e-mails from Thunderbird. Does anyone have any solution available?

This fix worked for me ! Both sending and receiving work again. Kiitos!
