When running the Server Availability Report in MessageStats Reports, the report returns no matching records
This data is taken from the MOM 2005 OnePoint Database and placed into the MessageStats Database. In order for MessageStats to obtain the Server Availability information for Exchange Servers, MOM would need to have the Exchange Management Pack for MOM 2005 installed on the MOM Server. If this has not been installed in your environment, this report will be blank
Install the Exchange Management Pack for MOM 2005 on the MOM Server to enable these reports.
