The Exchange management packs send you to the product knowledge articles online, rather than including the knowledge article in the management pack itself. When you view a knowledge article for the Exchange 2007 Management Pack, you might be confused to see references to "MOM Rule Path" and "MOM Rule Name". These are knowledge articles that apply to both Microsoft Operations Manager (MOM) 2005 and System Center Operations Manager 2007. The Explanation and User Action sections should give you the information you need to resolve the issue, whether you're using MOM or Operations Manager.
