Microsoft Service Message Queue


To enable archival of IMs, the archiving server role requires the Microsoft Service Message Queue (MSMQ) feature, as described in [MS-MQSD], to be configured on all Standard Edition servers and Enterprise pool front-end servers where archiving is enabled.

Similarly, to enable monitoring of services, the monitoring server role requires MSMQ to be installed on all Standard Edition Servers, Enterprise pool front-end servers, and mediation servers that are monitoring Call Data Records.
