Unified Communications Client API exposes strongly typed category instance interfaces and events to encapsulate contact related category instances that are defined and used by Microsoft Office Communicator. With these interfaces and events, a Unified Communications Client API client interoperates with Office Communicator without requiring detailed knowledge of the proprietary category schemas. The Unified Communications Client API application can also use these interfaces and events as the data model of the contact management by the application. However, the application developer must exercise caution to avoid any potential conflict between the application's implementation and the Office Communicator implementation, if the application might interoperate with Office Communicator.

The following table shows the Communicator-defined contact-related category names and their corresponding Unified Communications Client API interfaces.

Type-specific category instances are obtained by querying interface on an IUccCategoryInstance object.
