Thunderbird profiles with 1 or more accounts

If you have a Thunderbird profile with one or more accounts, you will see the new Thunderbird Account Hub flow:

  1. Click Thunderbird app menu > New Account > Email
  2. Follow the flow by entering your name, email address, and if required, your two factor authentication code for your Exchange email account.
    Note: you do not need to enter your password in the Password field of the first dialogue. You will enter your password in a separate, branded panel provided by Microsoft (not Mozilla) as part of their OAuth implementation.
