Recently, my College switched to Outlook 365 mail.

I'm running the latest 64 bit Thunderbird on Windows 10.

We use OAuth2 for incoming and outgoing.

Incoming server is outlook.office365.com. OAuth2 is an authentication option. Fine. I use Microsoft Authenticator, and it works.

But, Thunderbird will not or cannot use OAuth2 on the SMTP sever, smtp-mail.outlook.com. It simply doesn't list the OAuth2 option. Even if I go back in and try to edit the server, it won't give me that option.

Other clients detect it fine.

Okay. Almost, but you pointed me in the right direction.

During account setup, I used smtp.office365.com.

That let me choose OAUTH2.

BUT, before actually clicking create, I changed the server back to smtp-mail.outlook.com, and created the account.

Finally!

I am using Thunderbird (64-bit) 115.6.0 on a raspberry pi. Trying to access the Outlook 365 account at my university. following some of the suggestions I've read, I initially just entered my email with no password and tried to set up the account. This failed as expected, but allowed me to then manually enter the server, port and authentication methods:

IMAP Server: outlook.office365.com IMAP Port: 993 IMAP Encryption: SSL/TLS Authentication: Oauth2

and for SMTP Server: smtp.office365.com port: 587 Connection Security: STARTTLS Authentication: OAuth2

and in both cases the user name is my full email address

I was able to successfully log in using our Duo authentication, but the mail only works for incoming and I cannot set emails, getting a login error. Any thoughts??

Thanks in advance.
