How to Perform Journal Migration for Office 365?

Journaling is an essential component of an organization’s preparation to respond to legal, regulatory, and compliance requirements. With journaling, companies can record communications through different channels and archive them. An organization’s ability to journal different classes of data is indicative of its compliance posture. While many organizations using on-premises solutions can manage it within their infrastructure, others have realized that they would need additional assistance when they use cloud computing. Journaling is a major challenge for Office 365/ Microsoft 365 users. Let us understand how to perform journal migration for Office 365/ Microsoft 365.

Why Perform Journal Migration for Office 365?

If you are migrating to Office 365/ Microsoft 365 and are using Exchange Online, you will need to perform a journal migration for Office 365 for compliance. Here are some advantages of journaling with Office 365.

  • You can use advanced capabilities such as Journal Report Decryption for storing clear-text copies of messages in journal reports.
  • Complex rules can be defined to guarantee the validation and immutability of messages.
  • Detailed chain-of-custody can be preserved for reports.
  • Alternate journaling mailboxes can be used to guarantee availability.
  • Advanced eDiscovery and search features can be used in Office 365/ Microsoft 365 to find information quickly.
  • Envelope journaling can be used for compact journal reports.

How to Perform Office 365 Journal Migration?

Microsoft does not allow Exchange Online mailboxes to be used as journal mailboxes. Consequently, you will have to perform an Office 365 hybrid migration or use a third-party archiving service for journaling.

Here are the different migration techniques that can be used for Office 365 journal migration.

Simple Microsoft 365/ Office 365 Journal Migration

In this case, shared mailboxes are used in Office 365 for retaining information about the chain-of-custody. The emails are reconstructed at the time of an audit.

Note that Microsoft prohibits the use of shared mailboxes that are used by multiple users explicitly for archiving. However, with appropriate licenses, eDiscovery, and retention policies can be applied to shared mailboxes for ensuring compliance.

Advanced Microsoft 365/ Office 365 Journal Migration

In the case of advanced journal migration, all the data after the migration is fully available for eDiscovery. This includes blind carbon copy (BCC) data, distribution list (DL) data, and all the other relevant information. All the migrated data is distributed accurately to individual mailboxes with complete integrity and chain-of-custody details.

Using Third-Party / On-Premises Archiving Infrastructure

The last option for journal migration for Office 365/ Microsoft 365 is to use an on-premises server (e.g. Exchange Server 2019) or a third-party arching system for journaling. With this implementation, the on-premises mailbox can be used as a common journaling mailbox for both environments.
