The Enable-UMServer cmdlet sets the status of a Unified Messaging server to enabled. This enables the Unified Messaging (UM) server to process UM calls.


Enable-UMServer -Identity <UMServerIdParameter> [-DomainController <Fqdn>]


Parameter Required Type Description




This parameter specifies the identifier for the Unified Messaging server that is being enabled. This is the directory object ID for the Unified Messaging server.




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 Enable-UMServer cmdlet sets the status of a Unified Messaging server. A Unified Messaging server has a logical status variable that is controlled by using the enable and disable cmdlets. A Unified Messaging server will not process any new calls unless it is in the enabled state. The status variable lets you start or stop call processing on a Unified Messaging server so that the Unified Messaging server can be brought online or taken offline in a controlled way.

To run the Enable-UMServer cmdlet, the account you use must be delegated the following:

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

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