Instances of this interface are used by the OnAddedToGroup and OnRemovedFromGroup members of the _IUccContactEvents interface.

The OnAddedToGroup event is received for each contact in a logged on user's contact list and for each group to which the contact belongs. When a client application has registered a user with Microsoft Office Communications Server, the server provisions the client with a contact list that includes such details as the group membership of each contact. For a given contact in the provisioned list, this event is raised for each group that contact is a member of.

In the course of a session, a local user can also add a contact to other groups or remove the contact from a group. These events are raised in response to corresponding group membership actions.
