How Server Settings Affect Client Functionality

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.

Many server settings have an impact on the features and functionality available to clients, as well as other aspects of the user experience. Table 1 provides an overview of how individual server settings map to specific effects on clients.

Note

This topic does not cover server settings for Communicator Web Access or Group Chat, each of which has a separate administration document. For details about Communicator Web Access, see the Communicator Web Access (2007 R2 Release) Administration Guide documentation. For details about Group Chat, see the Administering Group Chat documentation.
