In Microsoft Exchange Server 2013, you can create mobile device mailbox policies to apply a common set of policies or security settings to a collection of users. After you deploy Exchange ActiveSync in your Exchange 2013 organization, you can create new mobile device mailbox policies or modify existing policies. When you install Exchange 2013, a default mobile device mailbox policy is created. All users are automatically assigned this default mobile device mailbox policy.

Windows Phone 7 mobile phones only support a subset of all Exchange ActiveSync mailbox policy settings. For a complete list, see Windows Phone 7 Synchronization. |
Overview of mobile device mailbox policies
You can use mobile device mailbox policies to manage many different settings. These include the following:
- Require a password
- Specify the minimum password length
- Require a number or special character in the password
- Designate how long a device can be inactive before requiring
the user to re-enter a password
- Wipe a device after a specific number of failed password
attempts
For more information about all the settings you can configure, see Mobile device policy settings.
Managing Exchange ActiveSync mailbox policies
Mobile device mailbox policies can be created in the Exchange Administration Center (EAC) or the Exchange Management Shell. If you create a policy in the EAC, you can configure only a subset of the available settings. You can configure the rest of the settings using the Shell.
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
Mobile device mailbox policy settings
The following table summarizes the settings you can specify using mobile device mailbox policies.

settings can be sent to the mobile device over a cellular data
connection. The default value is |
Allow non-provisionable devices |
This setting specifies whether mobile devices that may not support application of all policy settings are allowed to connect to Exchange 2013 by using Exchange ActiveSync. Allowing non-provisionable mobile devices has security implications. For example, some non-provisionable devices may not be able to implement an organization’s password requirements. |
