This Exchange TechNet Wiki page contains information about using Windows Phone 7 based Exchange ActiveSync clients in an Exchange enterprise environment.

Note
If you look for information around what EAS policies are supported by non-Windows Phone 7 devices, see the Exchange ActiveSync comparison table.

Supported Exchange ActiveSync Policies

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:

• Password Required (this is the only policy available on Exchange 2003 SP2) 
• Minimum Password Length
• Idle Timeout Frequency Value
• Device Wipe Threshold
• Allow Simple Password
• Password Expiration
• Password History

The following policies will always return "TRUE" (see table later on this page):  

• Disable Removable Storage
• Disable IrDA
• Disable Desktop Sync
• Block Remote Desktop
• Block Internet Sharing

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:

• Create a dedicated Windows Phone 7 EAS policy and associate it with mailbox users that use Windows Phone 7 devices.
• Set the AllowNonProvisionableDevices property to true in the default EAS policy already configured.
• Re-configure the default EAS policy within the Exchange organization, so it only has the policies listed above configured.

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.

Tip
Did you know you can access your mailbox using the OWA Premium version from Internet Explorer on a Windows Phone 7 device? To do so you need to enable "Desktop version" under "Website preference" on the Internet Explorer "Settings" page. The UI experience is actually quite good since you can zoom in on the navigation pane and specific settings in the Exchange Control Panel (ECP). It's easy to access the archive mailbox and enable or edit OOF settings etc.

Supported Exchange Server Versions

• Exchange Server 2010
• Exchange Server 2007
• Exchange Server 2003 SP2
• Exchange 2007 Online (BPOS)
• Exchange 2010 Online (Office 365)

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.

Why All These Missing Enterprise Features?

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.
