Just can't get enough of IT

When you encounter a situation where the transport queues are filling up or you just want to get messages out of a transport queue for further usage, you have to export the messages to the file system.

With Exchange 2007 you could easily utilize the Export-Message cmdlet to export suspended messages from a transport queue:

Get-Message -Queue MYSERVER\29489 | ?{$_.Status -eq "Suspended"} | Export-Message -Path D:\MessageExport

With Exchange Server 2010 or newer the Path attribute had been removed from the Export-Message cmdlet. The cmdlet now returns a binary object that needs to be assembled to a readable text message.

You can only export suspended messages, as the transport service might take precedence on non suspended messages. You can either suspend the queue or suspend single messages. The following example for Exchange Server 2010 or newer suspends the messages, but not the queue itself.

Identify the queue holding messages to be exported

Beispiel: Auflistung der Warteschlage auf Server MCMEP01

Get-Queue -Server MCMEP01

Suspend all Messages in Queue MCMEP01\Submission

Get-Queue MCMEP01\Submission | Get-Message ResultSize Unlimited | Suspend-Message

Fetch all messages to an array and export all messages to the local file system. You can either export all messages by just enumerating the messages or by using the message subject as the file name. Using the message subject posed the risk that the subject might contain a character that is not allowed for file names.

$array = @(Get-Message -Queue MCMEP01\Submission -ResultSize Unlimited | ?{$_.Status -eq "Suspened"})

$array | ForEach-Object {$m++;Export-Message $_.Identity | AssembleMessage -Path ("E:\Export\"+$m+".eml")}

$array | ForEach-Object {$m++;$filename="E:\Export\"+$m+"_"+$_.subject+".eml"; Export-Message $_.identity | AssembleMessage -path $filename}

The messages exported to the local file system can now be copied to the Exchange Transport Replay folder, which exists on each Exchange Server having an Exchange 2010 Hub Transport role or Exchange 2013/2016 Mailbox role.

• $exinstall\TransportRoles\Replay

After successful export of all suspended messages you want to delete the suspended messages from the queue. Ensure to use -WithNDR $false as otherwise all senders will receive a Non Delivery Report (NDR).

Get-Queue MCMEP01\Submission | Get-Message -ResultSize Unlimited | ?{$_.Status -eq "Suspened"} | Remove-Message -WithNDR $false

Messages saved to the Replay folder will be picked up the transport service. When a messages is picked up, the file extension changes to .TMP. You will not be able to delete a file at this point as the file is locked by the transport service. After a message file has been processed successfully, the file is deleted by the transport service. If there is any issue with the message file the file extension will change to .BAD.

This is a wrap-up of an older post that had originally been published on my former website.

Even though that this post focusses on Exchange 2010 transport agents, you will get an understand on what is required to create an Exchange 2013/2016 aka Version 15 transport agent.

Visual Studio Project

Writing your own transport agent for Exchange 2010 is not really complicated. With a Visual Studio C# Class project you are ready to go.

The follow picture shows the Visual Studio Solution as it has been used for the Message Modifier Solution.

Besides the C# class the solution contains the following Powershell script to simplify development and deployment:

• Add-TransportAgent.ps1
  Installs the transport agent on the productive Exchange Server
• Remove-TransportAgent.ps1
  Uninstalls the transport agent on the productive Exchange Server
  See Technet Gallery https://gallery.technet.microsoft.com/Remove-a-custom-Exchange-1cd30e92
• Build-DeploymentPackage.ps1
  Copy all required DLLs, Powershell scripts and the deployment configuration file to a dedicated folder
• install.ps1
  Installs the transport agent on the development Exchange Server
• uninstall.ps1
  Uninstalls the transport agent on the development Exchange Server

The transport agent intercepts a message from a given sender address and performs the following actions:

• If the message has attachments with file names starting with "WORKBOOK_" the attachments are renamed to the following format:
  
  [yyyyMMdd] [EMAIL SUBJECT]-[NUMBER].[ORIGINAL EXTENSION]
   
• The subject is rewritten from the format
  
  [dd.MM.yyyy] [SUBJECT TEXT]
  to
  [yyyyMMdd] [SUBJECT TEXT]

// AttachmentModify  
// ----------------------------------------------------------  
// Example for intercepting email messages in an Exchange 2010 transport queue  
//   
// The example intercepts messages sent from a configurable email address(es)  
// and checks the mail message for attachments have filename in to format  
//   
//      WORKBOOK_{GUID}  
//  
// Changing the filename of the attachments makes it easier for the information worker  
// to identify the reports in the emails and in the file system as well.

Sometimes you might be interested in gathering a list of all computer from an Active Directory domain in preparation for migration.

You can gather a list of all computer objects using the following command.

# Fetch a sorted list of all computer objects
Get-ADComputer -Filter * -Property * | Sort-Object Name 

The wildcard used with the Property parameter fetches all available attributes for a computer object. Check the available attributes in the result set to identify the attributes you are interested in.

# Example output for the first computer object gathered from Active Directory
(Get-ADComputer -Filter * -Property * | Sort-Object Name)[0]

As a next step, you gather the selected information and 

# Fetch data for an operating system overview, sorted by property Name only
Get-ADComputer -Filter * -Property * | Sort-Object Name | Select Name,OperatingSystem,OperatingSystemServicePack,OperatingSystemVersion 

# Fetch data for an operating system overview, sorted by property OperatingSystem first, then Name 
Get-ADComputer -Filter * -Property * | Sort-Object OperatingSystem,Name | Select Name,OperatingSystem,OperatingSystemServicePack,OperatingSystemVersion 

You can export the gathered information to a comma separated file easily using the Export-Csv cmdlet.

# Export the gathered and sorted information to a CSV file using a semicolon as the delimiter
# Adjust the file path for the CSV file to fit your environment
Get-ADComputer -Filter * -Property * | Sort-Object OperatingSystem,Name | Select Name,OperatingSystem,OperatingSystemServicePack,OperatingSystemVersion | Export-Csv -Path C:\SCRIPTS\ComputerOverview.csv -NoClobber -NoTypeInformation -Delimiter ';'

Description

This script removes the proxy address(es) for a selected protocol from mail enabled public folders.

Any proxy address with a given protocol is removed from the proxy addresses list.

The script can fix the alias of mail enabled public folders as well. The code used is based opon a blog post by Shay Levy.

Examples

# EXAMPLE 1
# Check mail enabled public folders for proxy addresses having "MS:" as a protocol type.
# Do not remove and update addresses, but log found addresses to RemovedAddresses.txt

.\Clean-MailEnabledPublicFolders.ps1 -ProtocolToRemove "MS:*" 

# EXAMPLE 2
# Check mail enabled public folders for proxy addresses having "MS:" as a protocol type.
# Remove and update addresses and log found addresses to RemovedAddresses.txt

.\Clean-MailEnabledPublicFolders.ps1 -ProtocolToRemove "MS:*" -UpdateAddresses

Description

This script connects either to Exchange Online or to a dedicated on-premises Exchange Server to export configured mailbox delegates and SMTP forwarding configurations.

The SMTP forwarding configurations are gathered from inbox rules and from mailbox forwarding settings.

• Cretenials to logon to Exchange Online and Office 365 when querying EXO mailboxes
• Utilizes GlobalFunctions PowerShell Module --> http://bit.ly/GlobalFunctions

Examples

# Example 1
# Connect to the on-premises Exchange Server mx01.varunagroup.de and export delegation and SMTP forwarding information
 
.\Get-DelegatesAndForwardingRules.ps1 -ExchangeHost mx01.varunagroup.de

# Example 2
# Connect to the on-premises Exchange Server mx01.varunagroup.de, export delegation and SMTP forwarding information and get verbose information on the objects worked on

 .\Get-DelegatesAndForwardingRules.ps1 -ExchangeHost mx01.varunagroup.de -Verbose 

# Example 3
# Connect to Exchange Online and export delegation and SMTP forwarding information

 .\Get-DelegatesAndForwardingRules.ps1 -ExchangeOnline
