Title: How to Change Priority of an E-mail Recipient Policy in Microsoft Exchange Server 2003
Objective: The objective of this demo/tutorial is to teach you how to change priority of an e-mail recipient policy in Microsoft Exchange Server 2003. You can define the order in which recipient policies are applied to recipients. For example, if you want users in Europe to have a specific set of addresses, you must create a recipient policy with your European users as members. Make the priority of the European recipient policy higher than the default policy, so that it applies to European users who are also members of the default policy.
