Thunderbird is an open source email client produced by Mozilla. This software offers an alternative to Outlook and the Outlook Web App that some users may prefer. These instructions were tested in Thunderbird version 24.1.1 and may differ for other versions. Additionally, the full version of Outlook and Outlook Web Access are both recommended over Thunderbird for users who prefer to have built-in functionality for calendaring, folder management, and access to the global address book.


  1. Open Thunderbird
  2. Go to Options and click on Account Settings
  3. Under Account Actions on the bottom-left, select 'Add Mail Account'
  4. Fill in the Name field (This part is just a matter of personal preference)
  5. Enter in your into the Email field and type in your password below.
  6. Click on the 'Continue' Button on the bottom-right and Thunderbird will attempt to automatically detect your server settings. This process usually fails so you may need to enter the following information manually:
    • Incoming settings:
      • Select IMAP from the dropdown menu
      • Type in the server hostname box
      • Select 993 from the Port dropdown menu
      • Select SSL/TLS from the SSL dropdown menu
      • Select Normal Password from the Authentication dropdown menu
    • Outgoing settings:
      • Type in the server hostname box
      • Select 587 from the Port dropdown menu
      • Select STARTTLS from the SSL dropdown menu
      • Select Normal Password from the Authentication dropdown menu
    • Username field:
  7. Once finished, all of the settings should look like this:
  8. Now click the Advanced Config button. This will open up the Thunderbird settings window shown below:
  9. Select the Outgoing Server option from the left-hand menu
  10. Make sure the outgoing server you just created (will be called is set to default and selected
  11. Click the Edit button
  12. Remove everything in the User Name field and put in your ONID user name instead:
  13. Click OK when you are finished, then OK again to close the main settings window
  14. Note: When you attempt to send your first email message, Thunderbird will prompt you for your ONID password. Enter that in and you should be good to go.

It may take a while for Thunderbird to download your mail if you have a large mailbox or slower network connection. If your mail doesn't appear at first, give it some time to catch up. After a few minutes your mailbox should load.
