    Proofpoint Email Continuity Administrators Guide

    Introduction

    Proofpoint Email Continuity is a cloud-based email continuity solution that enables members of your Organization to continue to receive and reply to email messages when your mail servers are temporarily off-line. It provides an always-on secondary email service for cloud services such as Office 365 and Google Apps, and platform agnostic support for on-premise solutions such as Microsoft Exchange.

    When Email Continuity is licensed, copies of messages to your Organization are stored in the Proofpoint Cloud Email Continuity Service for a period of 30 days or 1 GB per mail box. Users have access to their messages using a Webmail portal to the Proofpoint Cloud, authenticating with either their Proofpoint IdP credentials or your Organization's supported SAML 2.0 Identity Provider (IdP).

    In the event of an outage, end users continue to send and receive emails via the Email Continuity Web Portal. Users can access the Email Continuity portal from within Outlook using the Continuity by Proofpoint folder in Exchange or with the Email Feedback for Microsoft Outlook Plug-in. Email Continuity is a no-maintenance service that mitigates the risk of email downtime and lost productivity.

    Email Continuity is also supported in an optimized web mail interface for iOS (Safari browser) and Android (Android browser) for mobile devices.

    How Email Continuity Works

    This section describes how the Email Continuity feature works.

    External Emails

    For external inbound emails, Proofpoint Enterprise Protection scans each message directed towards your primary email solution for viruses and spam. After scanning, a copy of each message is compressed, encrypted, and transmitted to the Proofpoint Email Continuity service. The administrator does not need to set up or configure anything.

    For external outbound emails, in order for the sender to store a copy of their email in Continuity, Proofpoint requires Exchange journaling rules to be configured as described below.

    Internal Emails

    For internal emails, Proofpoint requires journaling rules to be configured on your Organizations Exchange Servers so that a copy of the journal emails can be sent to Pro
