GMS 2.0.1 Windows 8.1 connection.

I upgraded our datasync server from ver 1.2 to GMS 2.0.1 last week so it would be easier to sync Windows 8 devices. I'm having issues with Windows 8.1 on a MS Surface Tablet connecting. The current Android and iOS devices seem to still be working and I can connect new Android and iOS devices.

I have not been able to create an exchange account with EAS or non EAS and connect the device like the documentation describes. Does any one have any tips for getting windows 8.1 to connect? I was able to create an account on the tablet using LDAP but it does use GMS when connecting.
