I am trying to update my Thunderbird settings to account for the new MSN authentication process. Everything worked fine checking the cookie settings and updating the authentication method for my MSN account imp server. When I went to update the outgoing server setting, there is no OAuth2 showing in the authentication box. Aside from normal password, there is encrypted password, Kerberos/GSSAPI and NTLM. I think my current version of Thunderbird, 128.1.0esr, is up to date. Are you able to explain to me what I need to do? Thank you for any assistance you can give.
