Outlook 2016 and Exchange 2010...
An issue came up when a user wants to use his personal laptop to connect for email.
All other machines work fine because they are joined to the domain, and Outlook is set up for them the first time while connected to the LAN. This PC of course can't do that.
So, yes we know that Outlook 2016 no longer supports EAS, or has the settings available to manually set up RPC over HTTP proxy, and this needs to come from autodiscover. Autodiscover is set up, and both the outlook connectivity and autodiscover tests pass on testconnectivity.microsoft.com.
BTW older versions of outlook and most phones running Outlook can use autodiscover and set themselves up fine.
What I am not finding anywhere is WHAT INFORMATION IS NEEDED IN THE AUTODISCOVER XML file? Surely if the requirement changed, there is a document somewhere with some insight on what to do.
