Trying get TB 115 to work with Outlook.com email account and OAuth2.

  • Outbound email will not work. SMTP Server authentication method does not show the drop down option for oauth2 (see attached screen shot).
  • I am using the server names, ports, etc from MS. No issues until forced changed to oauth2.
  • Inbound email is working (IMAP) with ouath2 and MS set to 2FID.
  • Gmail works fine through TB.

Thank you for your help.

Thank you sfhowes. I tried those addresses before, but this time I rebooted. Outbound works fine now.
