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 "In-Place eDiscovery" entry in the Messaging policy and compliance permissions topic.


Parameter Required Type Description




The InPlaceHoldIdentity parameter specifies the GUID of an In-Place Hold. Use this parameter to search for an In-Place Hold that a user is placed on. GUIDs of all In-Place Holds that a user is placed on are added to the user's InPlaceHolds property. You can retrieve the property by using the Get-Mailbox cmdlet.




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 Identity parameter specifies the name of the search query. If a name isn't provided, all mailbox search queries are returned.

To improve the performance of this cmdlet in Exchange Online, some mailbox search properties aren't returned if you don't specify the name of a mailbox search. These properties are:

  • SourceMailboxes

  • Sources

  • SearchQuery

  • ResultsLink

  • PreviewResultsLink

  • Errors

To view these properties, you have to provide the name of a mailbox search.




The ResultSize parameter specifies the maximum number of results to return. If you want to return all requests that match the query, use unlimited for the value of this parameter. The default value is 1000.




This parameter is reserved for internal Microsoft use.
