You can use IMAP to access your mail on Exchange, which allows you to continue using Thunderbird even if your email is handled by an Exchange server. Using Exchange this way is not optimal, however, since only “full Exchange” use (e.g. with Outlook or OWA) gives you the complete range of features that Exchange offers (including calendar and resource scheduling, a centralized Contacts list, and access to BU directory information). However, for those people who prefer to continue with use of Thunderbird, at least for email, IMAP access makes that possible.

NOTE: If you are switching from ACS to Exchange after your account has been migrated to Exchange, you will first want to switch for in your Account Settings. That might be all you need to do. However, if you experience any problems, you will find a link to return to this page to make sure your settings are correct.

Configuring Exchange in Thunderbird

  1. Launch Thunderbird.
  2. If this is the first time you have used Thunderbird, you will likely be able to skip to step 3. Otherwise, go to Tools-Account Settings, click on the Account Actions button and choose to Add Mail Account…
  3. Complete the Mail Account Setup window as shown below, replacing Pat Employee’s information with your own. Then click on Continue.AddAccount
  4. Thunderbird will then try to guess at BU’s mail server settings. It will guess wrong, so, if you’re on a Mac, you should click on the Stop or Configure button. Otherwise, just let it go to the point of failure. Then, configure the settings as shown below. Among the other changes you will need to make, be sure to change the Incoming mail server from POP to IMAP and change the authentication settings to match those shown below. IMPORTANT: If it’s presented as an option, select Normal Password authentication.Setup
  5. Next, click on Re-test Configuration and then you should be able to Create Account. If not, try clearing your Password field and deselect “Remember password.” Then click again on Create Account and give your password if prompted.
  6. Once the account is created, you should click on OK if you wish this to be your default account.
  7. Finally, if you have any folders on the Exchange server, you might need to go to File-Subscribe in order to select and Subscribe to them so they will display. Then click on OK.
