Before you try to test or verify any end-user functionality, verify that the changes you made to enable users have been replicated by the Office Communications Server User Replicator. The User Replicator logs an event with ID 30024 when replication completes successfully.
To verify that users were enabled
Log on to a server with the Office Communications Server 2007 R2 administrative tools as a member of the RTCUniversalUserAdminsgroup or with equivalent user rights.
Click Start, point to All Programs, point to Administrative Tools, and then click Office Communications Server 2007 R2.
Expand the forest node and the pool node, and then click Users.
Confirm that the users you successfully enabled for Office Communications Server are listed.
