set to |
Require encrypted S/MIME messages |
This setting specifies whether S/MIME messages must be encrypted. |

Note: |

You don't have to specify all policy settings when you create a new Exchange ActiveSync mailbox policy. Any policy setting you don't explicitly set will keep its default value. |
Exchange ActiveSync mailbox policies can be created in the Exchange Management Console or the Exchange Management Shell. If you create a policy in the EMC, you can configure only a subset of the available settings. You can configure the rest of the settings using the Shell.
When you install Exchange 2010, a default Exchange ActiveSync mailbox policy is created. The default policy is automatically applied when a new user is created through the EMC or the Shell.
You don't have to assign a user to an Exchange ActiveSync mailbox policy. The following table summarizes the policy settings used if you don't assign a user to a policy.

Windows Phone 7 Synchronization
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
Exchange ActiveSync Mailbox Policy Examples
The following figure shows how Exchange ActiveSync mailbox policies can be created to control different settings for three groups of users.
