  • Within Thunderbird, click on your email address, on the left side of the Thunderbird window.
  • Under Advanced Features, click Manage Folder Subscriptions.
  • A pop-up window will open, entitled Subscribe, which will display all of the existing folders for your email account. Place a check to the right of any folders you would like to be able to view within Thunderbird.

 Manage Folder Subscriptions

Note: You will need to click the arrows to the left of any expandable folders in order to be able to view and select any sub-folders for subscription.

  • Once you have selected all of the folders you would like to be able to view, click Subscribe > OK.
  • You will now see the selected folders underneath your email address within Thunderbird.

Important: The new folders will not automatically populate with your email messages. When you click on a folder to view the contents, Thunderbird will then sync your email for the selected folder.
