How Server Settings Affect Client Functionality

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 Administering Communicator Web Accessdocumentation. For details about Group Chat, see the Administering Group Chatdocumentation.
