I'm trying to change Thunderbird's authentication method for sending messages (SMTP), but OAuth2 does not appear as one of the Authentication Method options. I do not have Office 365. Please advise! Thank you.

Don't know how to post a screenshot without showing too much info! The SMTP Server Authentication Method dropdown box gives only these options: No Authentication; Normal Password; Encrypted Password; Kerberos / GSSAPI; and NTLM. There is no option for OAuth2.
