Applies to: Exchange Server 2016

This cmdlet is available only in on-premises Exchange Server 2016.

Use the Remove-MailboxImportRequest cmdlet to remove fully or partially completed import requests. Completed import requests aren't automatically cleared. Requests need to be removed by using the Remove-MailboxImportRequest cmdlet. Multiple import requests can exist against the same mailbox if you provide a distinct import request name.

This cmdlet is available only in the Mailbox Import Export role, and by default, that role isn't assigned to a role group. To use this cmdlet, you need to add the Mailbox Import Export role to a role group (for example, to the Organization Management role group). For more information, see the "Add a role to a role group" section in Manage role groups.

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

Removing a partially completed import request removes the request from the Microsoft Exchange Mailbox Replication service (MRS) job queue. Any import progress that was made until the removal won't be reverted.

Remove-MailboxImportRequest -Identity <MailboxImportRequestIdParameter> [-Force <SwitchParameter>] <COMMON PARAMETERS>

Remove-MailboxImportRequest -RequestGuid <Guid> -RequestQueue <DatabaseIdParameter> <COMMON PARAMETERS>

COMMON PARAMETERS: [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

This example removes the second import request for Ayla's mailbox Ayla\MailboxImport1.

Remove-MailboxImportRequest -Identity "Ayla\MailboxImport1"

This example cancels the import request by using the RequestGuid parameter for a mailbox or archive on MBXDB01.

Remove-MailboxImportRequest -RequestQueue MBXDB01 -RequestGuid 25e0eaf2-6cc2-4353-b83e-5cb7b72d441f

This example removes all completed import requests.

Get-MailboxImportRequest -Status Completed | Remove-MailboxImportRequest

The parameter set that requires the Identity parameter allows you to remove a fully or partially completed import request.

The parameter set that requires the RequestGuid and RequestQueue parameters is used for MRS debugging purposes only.

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 "Import Export" entry in the Recipients Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identity of the import request. By default, import requests are named <alias>\MailboxImportX (where X = 0-9). If you created the request using the Name parameter, use the following syntax: <alias>\<name>.

You can't use this parameter in conjunction with the RequestGuid parameter.




The RequestGuid parameter specifies the unique identifier for the import request. To find the import request GUID, use the Get-MailboxImportRequest cmdlet. If you specify the RequestGuid parameter, you must also specify the RequestQueue parameter. You can't use this parameter in conjunction with the Identity parameter.




The RequestQueue parameter identifies the request based on the mailbox database where the request is being run. You can use any value that uniquely identifies the database. For example:

  • Database GUID

  • Database name

You can't use this parameter with the Identity parameter.




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.




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.




PARAMVALUE: SwitchParameter




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.
