Title: How to Configure Downgrade High Priority E-mail Bound for X.400 for MailBox-Enabled Users in Microsoft Exchange Server 2003

Objective: The objective of this demo is to teach you how to configure downgrade high priority e-mail bound for X.400 for mailbox-enabled users in Microsoft Exchange Server 2003. For mailbox-enabled users, you can select an option that automatically downgrades e-mail that is set for high priority delivery to an X.400-type e-mail address. This downgrade causes the outbound e-mail to conform to original 1984 X.400 conventions.
