"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Activesync is for mobile devices, but your screen shots look like you are connecting via a PC. Outlook.com is the for the mobile device connectivity, or you can use the native email app on the mobile devices. If you are using your computer as the screen shots suggests, that is why the activesync connectivity is failing.

You may have a internal DNS issue.  See if you can ping your active URL from the computer.  You may have firewall blocking ping response, but if it resolves the correct IP then it is not a DNS issue.

The native Windows 10 mail app would support EAS connections to Exchange but the Outlook client will not--this is by design.  If Outlook, the native connection required is RPC/HTTP or MAPI/HTTP.  MAPI/HTTP has been the new standard--beginning with Exchange 2013.
