2. On Office Communications Server 2007, use Client Version Filtering to allow only clients with the most current updates installed, as listed in Apply Office Communications Server 2007 Updates, to sign in.

3. On Office Communications Server 2007, use Client Version Filtering to block Lync Server 2010 clients from signing in. Follow the steps described in "Configuring Client Version Filtering" at https://go.microsoft.com/fwlink/p/?LinkId=206665 to add the version filters listed in the following table.
