This is not a new topic and has been discussed for quite some time.
Exchange ActiveSync mailbox policies let you apply a common set of policy or security settings to a user or group of users. The following table summarizes the settings you can specify using Exchange ActiveSync mailbox policies.
Everything is ver well detailed in :

However, I wanted to make sure the following part would be seen :)
If you have Windows Phone 7 mobile phones in your organization, these phones will experience synchronization problems if certain Exchange ActiveSync mailbox policy properties are configured. To allow Windows Phone 7 mobile phones to synchronize with an Exchange mailbox, either set the AllowNonProvisionableDevices property to "TRUE" or only configure the following Exchange ActiveSync mailbox policy properties:
- PasswordRequired - MinPasswordLength - IdleTimeoutFrequencyValue - DeviceWipeThreshold - AllowSimplePassword - PasswordExpiration - PasswordHistory - DisableRemovableStorage - DisableIrDA - DisableDesktopSync - BlockRemoteDesktop - BlockInternetSharing
