This topic explains how to use the Exchange Management Console and the Exchange Management Shell to disable Unified Messaging (UM) on Microsoft Exchange Server 2007. When you disable Unified Messaging on a computer that is running Exchange Server 2007, you prevent the UM server from answering Unified Messaging incoming calls. You can choose to either disconnect all calls immediately or wait for existing calls to be processed before disabling the Unified Messaging server.
To perform this procedure, the account you use must be delegated the Exchange Server Administrator role and be a member of the local Administrators group for the target server.
For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.
In the console tree of the Exchange Management Console, expand the ServerConfiguration node, and then click the Unified Messaging node.
In the result pane, select the Unified Messaging server to disable.
In the action pane, click Disable immediately.
Note: When you select the Disable immediately option, the Unified Messaging server disconnects all calls that are connected to the Unified Messaging server. When you select the Disable after completing calls option, the Unified Messaging server will not accept new calls and will not be disabled until all calls have been processed.
In the confirmation dialog box, click Yes to continue.
Run the following command:
Disable-UMServer -Identity ExUMSrv -Immediate $true
For information about syntax and parameters, see Disable-UMServer.
