As an administrator, you then delete this user from Active Directory. Through the Exchange Server 5.5 Administrator program, you add the Exchange 2000 server to the list of servers to which Exchange Server 5.5 replicates public folders. You encounter the error when you open Exchange Service Manager and attempt to view the properties of the deleted user in the Client Permissions box on the Permissions tab of the Public Folder properties dialog box.
