The November 2010 updates were just released for OCS 2007 R2 and the Clients (Communicator, Communicator Phone Edition, Live Meeting, and the Live Meeting Add-In). As Aaron Tiensivu reports, this round of udpates is apparently the true CU7 (the previous release was apparently just a CU6 add-on hotfix for the Routing Group Service).

Equally surprisingly is that this does not seem to be officially [...]

AD Attributes Required to Enable a User for OCS

OCS Federated Partner Trust Level

I recently discovered the concept of ‘Trust Level’ with OCS federated partners (I thought all partners were treated equal once they were added as a federated partner).  It turns out that one partner can be ‘trusted’ more than another partner depending on how the federation is configured on the OCS 2007 R2 Access Edge.

The element [...]
