The Remove-UMDialplan cmdlet deletes an existing Unified Messaging (UM) dial plan.


Remove-UMDialPlan -Identity <UMDialPlanIdParameter> [-DomainController <Fqdn>]


Parameter Required Type Description




This parameter specifies the identifier for the UM dial plan that is being deleted. This is the directory object ID for the UM dial plan.




To specify the fully qualified domain name of the domain controller that writes this configuration change to the Active Directory directory service, include the DomainController parameter on the cmdlet.

Detailed Description

The Remove-UMDialplan cmdlet is used to delete an existing UM dial plan from Active Directory. The administrator must make sure that the UM dial plan is not being used by other UM objects such as UM mailbox policies or UM IP gateways. When you are deleting an existing UM dial plan, the cmdlet verifies that the specified UM dial plan is not referenced by a Unified Messaging server, UM IP gateway, or UM mailbox policies. The only benefit gained from deleting an obsolete UM dial plan is to reuse the name or perform general Active Directory housekeeping.

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

  • Exchange Organization Administrator role
