Use the Remove-TransportRule cmdlet to remove a transport rule from a Hub Transport server or an Edge Transport server.

Remove-TransportRule -Identity <RuleIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

The Remove-TransportRule cmdlet permanently removes a transport rule that's no longer required. On Hub Transport servers, the cmdlet removes the rule from Active Directory. On an Edge Transport server, the cmdlet removes the rule from the local Active Directory Lightweight Directory Services (AD LDS) instance.

To temporarily disable a transport rule without removing it, use the Disable-TransportRule cmdlet instead.

For information about the Transport Rules agent, see Overview of Transport Rules.

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 rules" entry in the Messaging Policy and Compliance Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the transport rule to be removed. Enter either the GUID or the name of the rule.

You can omit the parameter label.




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 removes a single transport rule. The WhatIf parameter is used to display what changes are about to be applied without committing those changes. If you remove the WhatIf parameter and run the command again, the transport rule is removed.
