Description

Mobile device mailbox policies define settings for mobile devices that are used to access mailboxes in your organization. The default mobile device mailbox policy is applied to all new mailboxes that you create. You can assign a mobile device mailbox policy to existing mailboxes by using the Set-CASMailbox cmdlet, or by editing the mailbox properties in the Exchange admin center (EAC).

Some mobile device mailbox policy settings require the mobile device to have specific built-in features that enforce these security and device management settings. If your organization allows all devices, you must set the AllowNonProvisionableDevices parameter to $true. This applies to devices that can't enforce all policy settings.

Some settings in this cmdlet are supported by Outlook for iOS and Android. For more information, see Leveraging Exchange Online mobile device policies.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Set-MobileDeviceMailboxPolicy -Identity "Sales Policy" -PasswordEnabled $true -AlphanumericPasswordRequired $true -PasswordRecoveryEnabled $true -AttachmentsEnabled $true -MaxInactivityTimeLock 15:00 -IsDefault $false

This example sets several policy settings for the mobile device mailbox policy Sales Policy.

Example 2

Set-MobileDeviceMailboxPolicy -Identity Management -PasswordEnabled $true -AlphanumericPasswordRequired $true -PasswordRecoveryEnabled $true -AllowCamera $true -AllowWiFi $false -AllowStorageCard $true -AllowPOPIMAPEmail $false

This example sets several policy settings for the mobile device mailbox policy Management.

Example 3

Set-MobileDeviceMailboxPolicy -Identity Default -PasswordEnabled $true -AlphanumericPasswordRequired $true -PasswordRecoveryEnabled $true -AllowWiFi $false -AllowStorageCard $true -AllowPOPIMAPEmail $false -IsDefault $true -AllowTextMessaging $true -Confirm $true

This example sets several policy settings for the mobile device mailbox policy Default and requires confirmation before applying the settings.
