⟩ Can I manage Exchange Server 2003 or Exchange 2000 Server by using Exchange Server 2007 management interfaces?
No. All administration of Exchange Server 2007 must be done by using the Exchange Management Console or the Exchange Management Shell. All administration of Exchange 2000 Server or Exchange Server 2003 must be done by using their respective administrative interfaces. The one exception to this rule is that you can use Exchange System Manager found in Exchange Server 2003 to perform most Exchange Server 2007 public folder administrative tasks.
