The previous answer of Ramiro seems to be correct, from Control Panel->
Mail you can configure Outlook as ActiveSync and seems to work.

The outlook 2016 autoconfiguration seems to start now with:

"GET
/autodiscover/autodiscover.json?Email=mihai.badici%40mydomain&Protocol=ActiveSync&RedirectCount=1
HTTP/1.1" 404 228

Probably the answer will list the server capabilities, I will try to dig ...
