This Exchange TechNet Wiki page contains information about using Windows Phone 7 based Exchange ActiveSync clients in an Exchange enterprise environment.
If you look for information around what EAS policies are supported by non-Windows Phone 7 devices, see the Exchange ActiveSync comparison table.
Its important to note that Windows Phone 7 devices only support a subset of the Exchange ActiveSync (EAS) policies available with Exchange 2003 SP2, Exchange 2007, and Exchange 2010. Currently, Windows Phone 7 supports the following EAS policies:
The following policies will always return "TRUE" (see table later on this page):
If you want to use EAS policies not on the above list for other mobile devices in the Exchange organization, you have the following options:
Note When using multiple EAS accounts with policies set, the policies will be merged to a most restrictive resultant set.
For specific error messages received when trying to synchronize a Windows Phone 7 device with an Exchange organization that doesn't respect one of the above options, see Windows Phone 7 fails to synchronize with error 0x85010013 or 0x8600C2B when connecting to Microsoft Exchange Server.
Features not in Windows Phone 7 RTM:
Important Although Exchange Server 2003 SP2 is supported, there's currently an issue with searching the GAL from a Windows Phone 7 device against this Exchange version. Read more in the following KB article: You Cannot Search the Global Address List with Windows Phone 7 when connecting to Exchange Server 2003.
It's important to note that Windows Phone 7 (WP7) primarily was developed as a consumer device and not an enterprise device. As a result there of many of the enterprise oriented features we had in Windows Mobile 6.x aren't available in WP7. However, now that WP7 is out, the Windows Phone 7 team can focus on improving WP7 further and they already do. In addition, since it's now possible to push out updates via the new "Phone Update" feature, it doesn't mean that you necessarily need to buy a new device or wait for the service provider to release a new build in order to benefit from features added after you got a WP7 device.
