Event callback method data. Returns IContact instance added or removed from a group.Namespace: UCCollaborationLib
Assembly: Microsoft.Office.Uc (in Microsoft.Office.Uc.dll)
Provides an instance of IContact that is added or removed from a group collection. Returned by IGroup.OnContactAdded and IGroup.OnContactRemoved. If you are maintaining the state of a group locally, you can update application state using the IContact provided by IGroupMemberChangedEventData instead of iterating on the changed IGroup as IContactCollection. Note that in the event a contact is removed, the removed contact is no longer available in the IGroup. You can only obtain the removed contact in this interface. The interface identifier (IID) of this interface is 4b3a2412-c149-4e52-a713-6cebcf47503e.
