  • When trying to setup an office 365 email account using Mozilla ThunderBird, we keep getting the message that our account is either not connected/authenticated.
  • Yet, we have followed all the steps that Microsoft and Mozilla advised:

1. Launch Thunderbird. Select +New, Existing Email Account from the 'hamburger' menu.

2. Enter your name and e-mail address. You can leave the password empty. Press Continue to have Thunderbird figure out where your mailbox is hosted. This should discover your account in Office 365.

The settings you see should be:

Username: Full Email Address Password:

Protocol: IMAP Incoming (IMAP): outlook.office365.com SSL Outgoing (SMTP): smtp.office365.com STARTTLS

3. Click Done to confirm the creation of your account. If you are prompted for your password, hit Cancel.

4. Navigate to Account Settings -> Server Settings.

5. Under Authentication method, select OAuth2.

6. Navigate to Account Settings -> Outgoing Server.

7. Under Authentication method, select OAuth2.

8. Close the Account Settings. Select your Inbox, and you should be prompted with the Office 365 login page followed by the Duo prompt.

Hi there, this could be the same issue as reported here:

https://support.mozilla.org/en-US/questions/1400644

Try this workaround:

Use the Thunderbird Config Editor to set the setting network.dns.disableIPv6 to true by clicking the button on the right of this setting line to toggle it to true (the default is false).

Regards, Tim
