Summary

This guide explains how to configure email archiving for your entire Office 365 tenant. You will create a journal rule in Microsoft Purview, then create a connector in the Exchange Admin Center that routes all journaled mail to MirrorWeb Insight.

Prerequisites

  • You must be an administrator on your Office 365 tenant. If you are not an Office 365 administrator, please send this guide to a member of your IT staff with the correct privileges.

  • You must have obtained your journal feed address (JFA) for email archiving from the MirrorWeb Insight platform. If you require assistance, please contact our onboarding team at onboarding@mirrorweb.com.

This guide walks you through archiving your entire tenant, which captures all users and email addresses on it. If you only need selected users or email addresses to be archived, refer to the guide "How do I set up email archiving on Office 365 for selected users?" instead.

Step 1: Set the undeliverable report address

In the Microsoft Purview Portal, set the address that receives a report whenever a journaled message cannot be delivered.

  1. Open your Microsoft Purview Portal. In the left-hand navigation bar, navigate to Settings.

  2. Select Data Lifecycle Management, then Exchange (legacy).

  3. Choose an Undeliverable report address. This is required if archiving ever fails and sends a report of the message and why it was blocked. The email address you choose must be outside of your domain, otherwise it will not be archived.
