Contact Group Management

Managing contact groups involves creating a group, adding a contact to a group, removing a contact from a group, and deleting a group. A contact group represented by an IUccGroup interface contains a collection of contacts returned by a query to the Contacts property.
Group Types
- User-Defined Group
User-defined groups represented by the enumeration UCC_GROUP_TYPE. UCCGT_USER_DEFINED_GROUP. The user-defined group is a simple group container to which your contacts can be added. You can add and remove contacts to a user-defined group using Unified Communications Client API. User-defined groups are always provisioned in-band and in expanded state. At the time a user is logged on to an Office Communications Server, her user-defined groups are sent to the client along with all other subscribed data. Office Communications Server sends all group members along with the group itself. - Distribution Group
The distribution group is represented by the enumeration UCC_GROUP_TYPE. UCCGT_DISTRIBUTION_GROUP. This is the same distribution group of contacts you use in your e-mail application to send group e-mail. With a distribution group, you can add contacts to your contact list in bulk and start IM and audio/video conferences with a single operation. The users contained within a distribution group are maintained globally by a server administrator. This means you are freed from the responsibility of adding, changing, and removing contacts from your list when they change in a distribution group. Office Communications Server provisions your subscribed distribution groups in collapsed state. You do not receive the individual distribution group members with the distribution group itself. A separate expansion request must be made out of band. The request is made to a Web service supplied by Office Communicator. The Web service URL is available when you query the ServerConfiguration category (IUccServerConfigurationCategory).
