UOmail

1. Start Thunderbird.

     • Windows and macOS: Three bars menu > Account Settings > Account Actions > Add Mail Account...
     • Linux: Three bars menu > Preferences > Account Settings > Account Actions > Add Mail Account...
2. Enter your name, email address, and Duck ID password. 
3. Select Continue.
   • This will load and then fail. A window with server settings will then pop up.
4. For the incoming server, select IMAP.
   • Server host name: outlook.office365.com
   • Port: 993
5. For the outgoing server, select SMTP.
   • Server host name: outlook.office365.com
   • Port: 587
   • TLS or Connection security: STARTTLS
6. Then, click Re-test.
7. The server should load, but you will need to choose the OAuth2 authentication method for both IMAP and SMTP.
   • This option will not appear until you have successfully re-tested the settings at least once.
8. When you have the correct authentication method chosen, select Done.
9. A new pop-up will appear with a Microsoft log in page. Enter your Duck ID password.
10. A Duo prompt will appear. Click Cancel to select the Remember me for 7 days option (recommended), then select your desired validation method to authenticate.
11. Next, the pop-up will show a Permissions requested page for Thunderbird that you will need to accept to complete the set up of your account.
12. If you are using Thunderbird as your default mail client, click Set as Default. Otherwise, click Skip Integration.
