We are in the process upgrading from exchange 5.5 to Exchange 2003 along with our Domain controller to 2003 running Active Directory. We have both Exchange servers up and running. Every night I migrated some mailboxes from the old to the new. The Exchange 2003 has a totally different look than 5.5. How do I view the things I use to view with Exchange Administrator in 5.5 such as Ditribution lists,Information Stores, Mailboxes, Connectors, Receipients, etc? What is the equivalent to Exchange Administrator in Exchange 2003? Can someone shed some light?
