Remarks
Form servers use a form advise sink object to implement IMAPIFormAdviseSink instead of including it with their form object. Therefore, form viewers should expect a failed call to a form's IUnknown::QueryInterface method to obtain a pointer to this interface.
Form servers call a viewer's IMAPIViewContext::SetAdviseSink method to register for notifications. A pointer to their IMAPIFormAdviseSink implementation is included as a parameter.
