Use the Remove-X400AuthoritativeDomain cmdlet to remove an X.400 authoritative domain. When you remove an X.400 authoritative domain, the X.400 authoritative domain object is deleted from the Active Directory directory service.

Remove-X400AuthoritativeDomain -Identity <X400AuthoritativeDomainIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

To run the Remove-X400AuthoritativeDomain cmdlet, the account you use must be delegated the following:

  • Exchange Organization Administrator role

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


Parameter Required Type Description




Use this parameter to specify a string value for the X.400 authoritative domain. Enter either the GUID or the name of the X.400 authoritative domain.




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 information from Active Directory, include the DomainController parameter on the command. The DomainController parameter is not supported on computers that have the Edge Transport server role installed. The Edge Transport server role writes and reads only to the local Active Directory Application Mode (ADAM) directory service.




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.


Error Description


The following code example shows how to remove the X.400 authoritative domain object for an X.400 authoritative domain named Sales.

Remove-X400AuthoritativeDomain -Identity Sales
