For all of my Office 365 clients, including my own setup from the Action Pack, Modern Authentication is enabled. I have run into multiple Outlook 2016 installations where the only way to get connected to Outlook is to add EnableADAL and set it to 1. These have been fresh Office 365 Business Premium installations, existing Office 2016 OEM installations, and on my Action Pack installation of Office 2016.

Some of them allow users to get updates before the main release while others provide updates at a later time.

If after running the Remote Connectivity Analyzer Office 365 issues are not fixed, try using Microsoft Support and Recovery Assistant. This tool should be installed on a computer as a standalone application.
