Configure Modern Authentication on Thunderbird

To use Thunderbird, you will need to be running version 77.0b1 or later which supports OAuth2 modern authentication. Please note that some revisions of Thunderbird appear to have issues resolving user name and password authentication, necessitating a down version install of the software. Version 102.7.0 appears to have this issue, necessitating a downgrade to 102.6.1. Future version updates may resolve this issue.

Please also note that at the present time, these settings will only allow the mailbox to receive mail. If the user wishes for Thunderbird to be able to send mail, while utilizing the multi-factor authentication of PingID, a change may be implemented to the mailbox by OU IT. The user will need to submit a request and state they wish to have authenticated SMTP mail enabled for their OU mailbox for Thunderbird usage. To configure Thunderbird, please proceed:


Configure Thunderbird for Microsoft 365

  1. To begin, launch Thunderbird. If you have other accounts configured, click on Local Folders on the left hand side. Select Email under the Setup Another Account section in the main window.
  2. On the Mail Account Setup window, enter the following:
    • Your name: Enter your name
    • Email Address: Enter your OU email address
    • Password: Your OU email password
  3. Click the "Configure manually..." button.
    • For Incoming server set hostname:
    • For Outgoing server set hostname:
    • Username for both servers: Your OU Email address
    • Leave all other settings blank or on autodetect
  4. Click Re-test. The port and connection security settings should change.
  5. Change authentication method for both incoming and outgoing servers to OAuth2.
  6. For incoming server settings should be:
    • Protocol: IMAP
    • Server name:
    • Port: 993
    • Connection Security: SSL/TLS
    • Authentication Method: OAuth2
    • User Name: Your OU Email address
  7. For outgoing server settings should be:
    • Server name:
    • Port: 587 (default)
    • Connection Security: STARTTLS
    • Authentication Method: OAuth2
    • User Name: Your OU Email address
  8. Click Done.
  9. If prompted to enter your password, do so.
  10. Now click OK.
  11. You will be prompted to enter your password on an OU log in page. The page may appear multiple times, and if Thunderbird requests permissions press Accept.
  12. You should now be redirected to authenticate through PingID Multi-factor Authentication.
  13. After authenticating, your mailbox will now load all your mail. Please note this step may take a while on first configuration.
