fix

Exchange Management must be enabled on each Directory and Resource Administrator (DRA) server in a Multi-Master Set.  Information such as whether or not Exchange Management is enabled, Preferred Exchange Server and User name and Password, is not replicated between the DRA servers in a Multi-Master Set.  However, information such as Exchange Policies, Exchange Rules and Exchange Naming Rules are replicated.

The Preferred Exchange Server information is not replicated to all the Secondary DRA servers in order to provide the flexibility to specify a local Exchange Server in the same site or physical location as that of the DRA server.
