Use the Set-TransportAgent cmdlet to modify 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 2007 organization.


Set-TransportAgent -Identity <String> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Priority <Nullable>] [-WhatIf [<SwitchParameter>]]


Parameter Required Type Description




Use this parameter to specify the display name of the transport agent to be modified. The length of the name cannot exceed 64 characters.




The Confirm parameter 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 parameter.




To specify the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to the Active Directory directory service, include the DomainController parameter on the command. The DomainController parameter is not supported on computers that run the Edge Transport server role. The Edge Transport server role reads from and writes to only to the local ADAM instance.




Use this parameter to specify the priority of the transport agent. The priority of the transport agent controls the order in which the transport agents process e-mail messages. The priority must be a value between 0 and the maximum number of transport agents. The default behavior is to append a new transport agent to the end of the priority list. Transport agents with a priority closest to 0 process e-mail messages first.




The WhatIf parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, 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 parameter.

Detailed Description

The Set-TransportAgent cmdlet is used to modify a transport agent on an Edge Transport server or a Hub Transport server.

To run the Set-TransportAgent cmdlet, the account you use must be delegated the following:

  • Exchange Server Administrator role and local Administrators group for the target server

To run the Set-TransportAgent cmdlet on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.
