User Experience during Phase 8 of Migration
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
This guide does not cover installation and configuration of new server roles and feature sets. Because of this, after the existing users have been moved to the new Office Communications Server 2007 R2 pool and received the new Office Communicator 2007 R2 client, some features may not be operational unless you have deployed the supporting server roles. For more information, see Deploying Office Communications Server 2007 R2.
