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 Import-DlpPolicyCollection cmdlet to import data loss prevention (DLP) policy collections into your organization.

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

Import-DlpPolicyCollection -FileData <Byte[]> [-Identity <DlpPolicyIdParameter>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Force <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

This example imports the DLP policy collection in the file C:\My Documents\DLP Backup.xml.

Import-DlpPolicyCollection -FileData ([Byte[]]$(Get-Content -Path " C:\My Documents\DLP Backup.xml " -Encoding Byte -ReadCount 0))

The Import-DlpPolicyCollection cmdlet imports all the settings of the DLP policies and the associated transport rules. You use the Export-DlpPolicyCollection cmdlet to export the DLP policy collection.

Importing a DLP policy collection from an XML file removes or overwrites all pre-existing DLP policies that were defined in your organization. Make sure that you have a backup of your current DLP policy collection before you import and overwrite your current DLP policies.

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 "Data loss prevention (DLP)" entry in the Messaging policy and compliance permissions topic.


Parameter Required Type Description




The FileData parameter specifies the DLP policy collection file you want to import.

For more information about the syntax required to use this parameter, see Exchange cmdlet syntax.




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 Force switch specifies whether to suppress warning or confirmation messages. You can use this switch to run tasks programmatically where prompting for administrative input is inappropriate. You don't need to specify a value with this switch.




The Identity parameter specifies the name of the DLP policy you want to import. The DLP policy must exist in the XML file you specify with the FileData parameter.




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.




This parameter is reserved for internal Microsoft use.
