About Email Continuity
Email Continuity is an alternative email service that takes the place of your
primary email system during an outage. When the service is activated, users can
access their email through an easy-to-use web-mail interface.
If the Outlook
®
Extension has been installed on end-user’s desktops, they can
continue to access their email using Outlook
®
in cached mode.
Email Continuity consists of the following components:
