office365 outlook setup - EAS: The server cannot be found.

EAS: The server cannot be found.
Outlook 2016 as part of Office365; cannot set up outlook for work: outlook.office365.com (even while signed in to OWA for work)
OWA works fine on the same computer: login.microsoftonline.com (bookmarked for OWA sign-in)

What is the correct Mail Server setting?
