Applies to: Exchange Online, Exchange Server 2016

This cmdlet is available in on-premises Exchange Server 2016 and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

Use the Clear-ActiveSyncDevice cmdlet to delete all data from a mobile device.

For information about the parameter sets in the Syntax section below, see Syntax.

The Clear-ActiveSyncDevice cmdlet will be removed in a future version of Exchange. Use the Clear-MobileDevice cmdlet instead. If you have any scripts that use the Clear-ActiveSyncDevice cmdlet, update them to use the Clear-MobileDevice cmdlet.

Clear-ActiveSyncDevice -Identity <MobileDeviceIdParameter> [-Cancel <SwitchParameter>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-NotificationEmailAddresses <MultiValuedProperty>] [-WhatIf [<SwitchParameter>]]

This example clears all data from the mobile device with the identity WM_JeffHay.

Clear-ActiveSyncDevice -Identity WM_JeffHay

This example clears all data from the mobile device for Tony Smith and sends a confirmation email message to tony@contoso.com.

Clear-ActiveSyncDevice -Identity WM_TonySmith -NotificationEmailAddresses "tony@contoso.com"

This example cancels a previously sent Clear-ActiveSyncDevice command request for Tony Smith's mobile device.

Clear-ActiveSyncDevice -Identity WM_TonySmith -Cancel $true

The Clear-ActiveSyncDevice cmdlet deletes all user data from a mobile device the next time the device receives data from the Microsoft Exchange server. This cmdlet sets the DeviceWipeStatus parameter to $true. The mobile device acknowledges the cmdlet and records the time stamp in the DeviceWipeAckTime parameter.

After you run this cmdlet, you receive a warning that states: "This command will force all the data on the device to be permanently deleted. Do you want to continue?" You must respond to the warning for the cmdlet to run on the mobile phone.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Exchange ActiveSync user settings" entry in the Clients and mobile devices permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identity of the device that you want to reset.




The Cancel switch specifies whether the command should be canceled. If you use the Cancel switch, a cancellation request is issued for the remote device wipe.




The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.




This parameter is available only in on-premises Exchange 2016.

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.




The NotificationEmailAddresses parameter specifies the notification email address for the remote device wipe confirmation.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.
