Exchange 2010

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

Topic Last Modified: 2015-03-09

Use the Export-Message cmdlet to copy a message from a queue on a computer that has the Hub Transport server role or the Edge Transport server role installed to a specified file path in a Microsoft Exchange Server 2010 organization.

Export-Message -Identity <MessageIdentity> [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

The Export-Message cmdlet copies messages from the Delivery queue, the Unreachable queue, or the poison message queue on a Hub Transport server or an Edge Transport server to a specified file path. Before you export a message, you must first suspend the message. Messages in the poison message queue are already suspended. You can use the Export-Message cmdlet to copy messages to the Replay directory of another transport server for delivery.

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 Transport Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the MessageIdentity integer. This is an integer that represents a particular message and an optional server and queue identity. The syntax for this parameter is as follows:

  • Server\QueueIdentity\MessageIdentity

  • QueueIdentity\MessageIdentity

  • You must include QueueIdentity when you use the Export-Message command. If no server name is used, the task runs on the local server.




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 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 exports a single message to the specified file path. Because the Export-Message cmdlet returns a binary object, you must use the AssembleMessage filter to be able to save the message content into a specified location.

Export-Message -Identity ExchSrv1\contoso.com\1234 | AssembleMessage -Path "c:\exportfolder\filename.eml"

This example retrieves all messages from the specified queue. The query results are then piped to the Export-Message command, and all the messages are copied to individual .eml files. The Internet Message IDs of each message are used as the file names. To accomplish this, the command does the following:

  • Retrieves all messages in a specific queue using the Get-Message cmdlet.

  • The result is pipelined into the ForEach-Object cmdlet which executes the following actions for each message:

    • Prepares a file name including full path using the temporary variable $Temp that consists of the Internet Message ID with .eml extension. The Internet Message ID field contains angled brackets (">" and "<") which need to be removed as they are invalid file names. This is done using the Replace method of the temporary variable.

    • Exports the message using the file name prepared.

Get-Message -Queue "Server1\contoso.com" | ForEach-Object {$Temp="C:\ExportFolder\"+$_.InternetMessageID+".eml";$Temp=$Temp.Replace("<","_");$Temp=$Temp.Replace(">","_");Export-Message $_.Identity | AssembleMessage -Path $Temp}
