Thunderbird will attempt to find the correct settings, but if it cannot, you may receive this message, which is normal.

Step 8

Click Done. Now the mailbox will appear and start to populate.

Step 9

Because the protocol Thunderbird uses to connect to Office 365 is different than clients like Apple Mail and Microsoft Outlook 2011 for Mac, it will use different folders for some of the primary folders. To be consistent, we highly recommend you follow these steps below to minimize confusion if you also use Office 365 web or a different desktop email client.
