Exchange 2010

Applies to: Exchange Server 2010 SP2, Exchange Server 2010 SP3

Topic Last Modified: 2015-03-09

Use the Start-ManagedFolderAssistant cmdlet to immediately start messaging records management (MRM) processing mailboxes that you specify.

Start-ManagedFolderAssistant -Identity <MailboxOrMailUserIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

The Managed Folder Assistant uses the retention policy or managed folder mailbox policy settings of users' mailboxes to process retention of items. This mailbox processing occurs automatically. You can use the Start-ManagedFolderAssistant cmdlet to immediately start processing the specified mailbox.

In Microsoft Exchange Server 2010 Service Pack 1 (SP1), the Start-ManagedFolderAssistant cmdlet has been changed. In the Exchange 2010 release to manufacturing (RTM) and Exchange Server 2007 versions, the Identity parameter specifies the Mailbox server to start the assistant and process all mailboxes on that server, and the Mailbox parameter specifies the mailbox to process. In Exchange 2010 SP1, the Mailbox parameter has been removed, and the Identity parameter now accepts the mailbox or mail user to process.

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 "Messaging records management" entry in the Messaging Policy and Compliance Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the mailbox to be processed. In cross-premises deployments, you can also specify a mail user who has a mailbox in the cloud.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf 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.

This example processes the mailbox for a user who has the alias Chris.

Start-ManagedFolderAssistant -Identity "Chris"

This example uses the Get-Mailbox command to retrieve all the mailboxes that resolve from the ambiguous name resolution (ANR) search on the string "Chr" in the domain DC01 (for example, users such as Chris Ashton, Christian Hess, and Christa Geller), and the results are piped to the Start-ManagedFolderAssistant cmdlet for processing.

Get-Mailbox -Anr Chr -DomainController DC01 | Start-ManagedFolderAssistant
