Exchange 2010

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

Topic Last Modified: 2015-03-09

Use the Install-TransportAgent cmdlet to register a transport agent on a computer that has the Edge Transport server role or the Hub Transport server role installed in a Microsoft Exchange Server 2010 organization.

Install-TransportAgent -Name <String> -AssemblyPath <String> -TransportAgentFactory <String> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

The Install-TransportAgent cmdlet is used to register a transport agent for use on an Edge Transport server or a Hub Transport server.

Transport agents have full access to all e-mail messages that they encounter. Exchange puts no restrictions on a transport agent's behavior. Transport agents that are unstable or contain security flaws may affect the stability and security of Exchange. Therefore, you must only install transport agents that you fully trust and that have been fully tested in a test environment.

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 "Transport agents" entry in the Transport Permissions topic.


Parameter Required Type Description




The AssemblyPath parameter specifies the location of the transport agent Microsoft .NET assembly. Universal Naming Convention (UNC) file paths can't be used.




The Name parameter specifies the display name of the transport agent to be installed. The length of the name can't exceed 64 characters.




The TransportAgentFactory parameter specifies the Microsoft .NET class type of the transport agent factory. The developer of the transport agent being installed provides the transport agent factory and related information. For more information, see the documentation provided by the developer of the transport agent.




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 DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory. The DomainController parameter isn't supported on the Edge Transport server role. The Edge Transport server role writes only to the Active Directory Lightweight Directory Services (AD LDS) instance.




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 shows how a fictitious antivirus application is installed on an Edge Transport server or a Hub Transport server.

Install-TransportAgent -Name "Antivirus for Exchange" -TransportAgentFactory "vendor.exchange.avTransportAgentfactory" -AssemblyPath "c:\Program Files\Vendor\TransportAgent\AvTransportAgentFactory.dll"
