This error indicates that the Test-UMConnectivity cmdlet can't conduct a local UM connectivity check because the Microsoft Exchange Unified Messaging service isn't running. Local UM connectivity checks are performed when Test-UMConnectivity is run interactively, in local mode, on the UM server or as part of the monitoring provided by the System Center Operation Manager (SCOM) management pack for Exchange Unified Messaging.

This event may occur because the Microsoft Exchange Active Directory Topology service can't start.

  • Restart the Microsoft Exchange Active Directory Topology service on the UM server.
