Outlook 2016 & Exchange Servers

So I rebuilt my Surface Pro 3 and was struggling to connect back to the corporate on premise Exchange Server which is 2010.  After a bit of research it turns out Outlook 2016 is trying to use Exchange Active Sync (EAS) to connect which Exchange 2010 and the two are not happy together.

I came across this article that gave a good overview of the issues as EAS works fine for mobile/tabley sync and Mail app as they support EAS.

So to make it work (I think), I added the following registry entry and then autodiscover finally worked, however it took a good few minutes to connect and resolve.  Just be paitient.

If your Exchange Server does not have MAPI over HTTP enabled, you’ll need to set a registry key to disable MAPI over HTTP. This will cause Outlook 2016 to fall back to RPC over HTTP.

DWORD: MapiHttpDisabled
Value: 1

Happy Outlooking now.
