A contact can also be moved to the "Other Contacts" group from a user-defined group. Moving a contact to the "Other Contacts" group involves removing the contact from the user-defined group with the IMessengerGroup::RemoveContact method.

The contact list is rebuilt by the event handler registered for the DMessengerEvents::OnContactRemovedFromGroup event.
