User Experience During Phase 3

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.

Because the users are still homed on the Office Communications Server 2007 pool at this point, there will be no change in user experience.
