The scope of a category is a collection of users and user groups who may:

  • Search for and find the chat rooms in this category and those below it.

  • Be added to the member or manager list of the category, its subcategories, and chat rooms.

When specified, the scope of a category must always be a subset of the scope of the parent category. Hence, scope can be narrowed, but never increased. See BeginSetScope(ChatRoomCategory, ICollection<GroupChatPrincipalSummary>, AsyncCallback, Object)
