Note: These instructions follow the version of the software noted above. For other versions, there may be some variation, but the information below should serve as a guide to get you started. To identify the version of your software, look for the About link in the software's main or Help menu.

  1. Open Thunderbird. The first time you launch Thunderbird after installing it, the Mail Account Setup will open.
    Note: If you are not opening Thunderbird for the first time, go to Tools > Account Settings... and from the Account Actions drop-down menu (bottom, left), select Add Mail Account... A window identical to the Mail Account Setup window will open. You can now follow the instructions below.

    • In the Email Address: field, enter your UMail address

    • In the Outgoing: field, enter, then change the number in the field next to SMTP from 25 to 465.
    • Click Re-test Configuration. Thunderbird will verify your settings. If successful, two green dots will appear next to the Incoming: and Outgoing: fields.
    • Click Create Account. A window will open asking if you want to make Thunderbird your default email client. Depending on your preference, click OK or Cancel.
  4. To view your email messages in Thunderbird, click Get Mail (top left). Then, to check that your outgoing mail settings are correct, use Thunderbird to send a message to your UMail address. The message should appear in your Thunderbird inbox.

Congratulations! Thunderbird is now configured to send and receive messages with your UMail account.
