Exchange Server 2019 is equipped with various tools that enable organizations to manage their email infrastructure. One of these tools is Script Agent It is one of the cmdlet extension agents and is used to extend the functionality of PowerShell cmdlets.

The Script Agent feature came into our lives with Exchange Server 2010.

What is Exchange Server Script Agent?

Script Agent in Exchange Server, or as it is often called in Turkish, Script Agent, is known as a cmdlet extension agent that is available in Exchange Server and is used to automate certain commands or operations during the runtime of cmdlets. Script Agentis used to extend the functionality of PowerShell cmdlets and provides administrators with the ability to perform additional actions while running the cmdlets.

Script Agent Basic Features and Functions

  • Script Agentallows additional commands to be run automatically when certain cmdlets are run. For example, it can automatically apply certain configuration tasks (security settings, protocol management, etc.) when a new mailbox is created.
  • Script Agent Configurations are usually managed via an XML file. Administrators can define custom scripts for certain cmdlets in this file and have these scripts called by the cmdlets.

If you want to set default options for mailboxes that do not inherit a specific configuration item from the database or server level, then Scripting Agent is for you!

As TechNet describes, Scripting Agent When you enable the cmdlet extension agent, this agent is invoked every time a cmdlet is run on a server running Minimum Exchange 2010. This includes not only cmdlets run directly by you in the Exchange Management Shell, but also cmdlets run by Exchange services, the Exchange Management Console (EMC), and the Exchange Control Panel (ECP).

Important Information for Exchange Server Script Agent

There are some points to consider and pay attention to before enabling Script Agent on Exchange Server:

  • The Scripting cmdlet extension agent is disabled by default. You must enable it manually.
  • The configuration file name should be ScriptingAgentConfig.xml
  • You must copy the ScriptingAgentConfig.xml file to each server yourself. You must ensure that the correct version of the ScriptingAgentConfig.xml file is copied to each server. Exchange does not replicate or manage this file in any way.
  • Administrative workstations will also need a ScriptingAgentConfig.xml file. It is your responsibility to manage the distribution of this file. The Exchange installer expects the script file to be present when installing a new Exchange server or installing administrative tools. Do not disable the Scripting Agent just to install a server/administrative workstation. You can manually create the necessary directory path and copy the ScriptingAgentConfig.xml file to the BinCmdletExtensionAgents folder.
  • In an AD site with multiple domain controllers, you are likely to encounter object not found errors. This is caused by one part of the Scripting Agent script being triggered against DC-1 and then the next part being triggered against DC-2. This will result in a failure on DC-2 because the object has not yet been replicated to DC-2. To deal with this, we will pin a domain controller.
  • Note that this does not mean hardcoding a DC. Hard coding is never a good idea as it can cause problems when a DC fails. Since the file is XML based, it can be edited with Notepad, but it may be easier to edit using an XML aware tool. Tools like XML Notepad may vary depending on your preference!
