Applies to: Exchange Server 2016

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

Use the Remove-Message cmdlet to delete a message from a queue on a Mailbox server or an Edge Transport server.

Remove-Message -Filter <String> [-Server <ServerIdParameter>] <COMMON PARAMETERS>
Remove-Message -Identity <MessageIdentity> <COMMON PARAMETERS>
COMMON PARAMETERS: [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]] [-WithNDR <$true | $false>]

This example removes all messages that meet the following criteria without generating NDRs:

  • The messages are sent by the sender

  • The messages are queued on the server Server1.

Remove-Message -Server Server1 -Filter {FromAddress -eq ""} -WithNDR $false

A message being transmitted to multiple recipients might be located in multiple queues. If you specify an Identity parameter, the message is removed from a single queue if that identity matches only a single message. If the identity matches more than one message, you receive an error. To remove a message from more than one queue in a single operation, you must use the Filter parameter. If you try to remove a message currently being delivered, the message status changes to PendingDelete. Message delivery isn't interrupted, but if the delivery fails and causes the message to re-enter the queue, it's then removed.

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 "Queues" entry in the Mail flow permissions topic.


Parameter Required Type Description




The Filter parameter specifies one or more messages by using OPath filter syntax. The OPath filter includes a message property name followed by a comparison operator and value, for example, {FromAddress -like "*"}. For details about filterable message properties and comparison operators, see Message filters and Use the Exchange Management Shell to manage queues.

You can specify multiple criteria by using the and comparison operator. Property values that aren't expressed as an integer must be enclosed in quotation marks (").




The Identity parameter specifies the message. Valid input for this parameter uses the syntax Server\Queue\MessageInteger or Queue\MessageInteger or MessageInteger, for example, Mailbox01\\5 or 10. For details about message identity, see the "Message identity" section in Use the Exchange Management Shell to manage queues.




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 Server parameter specifies the Exchange server where you want to run this command. You can use any value that uniquely identifies the server. For example:

  • Name

  • FQDN

  • Distinguished name (DN)

  • Exchange Legacy DN

If you don't use this parameter, the command is run on the local server.

You can use the Server parameter and the Filter parameter in the same command. You can't use the Server parameter and the Identity parameter in the same command.




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.




The WithNDR parameter specifies whether a non-delivery report (NDR) is returned to the sender of a message. The default value is $true. This parameter can be used with both the Identity parameter and Filter parameter sets.
