Exchange 2010

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

Topic Last Modified: 2015-03-09

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 2010 organization.

Set-TransportAgent -Identity <TransportAgentObjectId> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Priority <Int32>] [-WhatIf [<SwitchParameter>]]

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




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 Priority parameter specifies 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 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 modifies the priority of a fictitious antivirus agent.
