/mcp• Configure the corporate email address of each user as an SMTP proxy address for the user. When setting up theUnity Connection IMAP account on user workstation, use the corporate email address of the user instead of the Unity Connection specific email address. In this way, users are insulated from changes to the Unity Connection-specific addresses if the SMTP domain is changed. • Create a separate Outlook address book for ViewMail users that is limited to the objects in the user search space if you are using search spaces to limit the objects that users can reach and do not want users to receive NDRs for unreachable objects.
