View transport agents in the transport pipeline
Applies to: Exchange Server 2013
You can use the Exchange Management Shell to view a list of transport agents in the transport pipeline on Microsoft Exchange Server 2013 Mailbox servers and Client Access servers. Specifically, the Get-TransportPipeline cmdlet shows information about the following types of transport agents in the transport pipeline:
Agents based on the SmtpReceiveAgent, RoutingAgent, DeliveryAgent, and StorageAgent classes in the Transport service on Mailbox servers.
Agents based on the SmtpReceiveAgentClass in the Mailbox Transport Delivery service on Mailbox servers.
Agents based on the SmtpReceiveAgentClass in the Front End Transport service on Client Access servers.
You can view a list of all the enabled transport agents that have encountered messages in the transport pipeline and the SMTP events they are registered on. For more information about transport agents, see Transport agents.

Use the Shell to view a list of transport agents in the transport pipeline
To use the Shell to view a list of transport agents in the transport pipeline on an Exchange server, run the following command:
Get-TransportPipeline | Format-List
To export the results to a text file named C:\My Documents\Transport Agents.txt, run the following command:
Get-TransportPipeline | Format-List > "C:\My Documents\Transport Agents.txt"
How do you know this worked?
Only transport agents that have encountered messages in the transport pipeline between the time when the transport service was started and the time when the Get-TransportPipeline cmdlet was run are displayed by the cmdlet. A transport agent that hasn't encountered a message in the transport pipeline won't appear in the results displayed by the Get-TransportPipeline cmdlet, even if that transport agent is enabled.
