With Microsoft Office Communications Server 2007 R2 Group Chat SDK you can participate in multiparty conversations that persist over time. Conversations occur in chat rooms, which are topic oriented, where you access controlled forums to post real-time messages to be shared with a group of users. You can use Microsoft Office Communications Server 2007 R2 Group Chat API to programmatically search for and manage chat rooms, as well as interact with other users in conversations.

The Group Chat API provides a managed-code platform for implementing group chat enabled applications that run on Microsoft Office Communications Server 2007 R2. The platform is multi-layered, and can be used for both administration and management of group chat services, as well as applications that participate directly in group chat conversations.

The classes are organized into two namespaces: Microsoft.Rtc.Collaboration.GroupChat and Microsoft.Rtc.Collaboration.GroupChat.Management . The GroupChat namespace provides basic functionality for group chat applications including the ability to send and receive chat messages, browse the chat room directory, and query chat history. The Management namespace provides advanced features used to manage chat rooms and to administer groups of chat users.
