Export-Message

This cmdlet is available only in on-premises Exchange.

Use the Export-Message cmdlet to copy a message from a queue on a Mailbox server or an Edge Transport server to a specified file path in your organization.

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

Syntax

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

Description

The Export-Message cmdlet copies messages from the Delivery queue, the Unreachable queue, or the poison message queue on Mailbox 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 Mailbox server for delivery.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

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

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.

Example 2

Get-Message -Queue "Server1\contoso.com" -ResultSize Unlimited | ForEach-Object {Suspend-Message $_.Identity -Confirm:$False

$Temp="C:\ExportFolder\"+$_.InternetMessageID+".eml"

$Temp=$Temp.Replace("<","_")

$Temp=$Temp.Replace(">","_")

Export-Message $_.Identity | AssembleMessage -Path $Temp}

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 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.
  • The ForEach-Object cmdlet also exports the message using the file name prepared.

Parameters

-Confirm

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.
