Email Journal Migration

Move your journals to a new platform

If you need to move an email journal (such as a Mimecast or an Exchange on-premises journal) to Microsoft 365, you’ll face a number of challenges, not least the fact there’s no journal service in Exchange Online.

Whilst it is possible to migrate the contents of a journal mailbox (or a journal archive) into Microsoft 365, this needs to be done with care. For example:

  • Migrating journals into one or more Microsoft 365 mailboxes breaks Microsoft’s licencing rules
  • Vital envelope metadata including BCC’d recipients & distribution list (DL) members must be preserved to ensure accurate eDiscovery
  • Your legal department will want an audit that proves every item has been successfully migrated & chain-of-custody preserved
  • Extracting your journal from a hosted platform such as Mimecast or Proofpoint can be extremely expensive
  • You may decide that you don’t want to ‘put all your eggs in one basket’ by migrating journals into Microsoft 365.

We can help you explore your best options for:
a) preserving and migrating the journals you’ve amassed to date, and

Be selective

Where appropriate to your business and legal remit, you can create policies to determine what gets migrated from your journal and where it gets migrated to.

E.g. move items <10 years to Microsoft 365, include users in the finance department only, migrate items > 10 years old to a secure cloud service

Discover your best journal migration options

This video explains the difference between conventional email journaling and what Microsoft 365 provides:

When it comes to deciding what to do with your legacy journals, there’s a number of routes you could take, including:

  • Migrating journals to Microsoft 365, then using Microsoft 365 retention policies & litigation hold to preserve email records going forwards
  • Running an email journal hosted in the cloud, and moving your historic journals to the same service

Each route has its own benefits and caveats depending on your business and compliance needs.

You may also want to extend your journaling to include the capture of other messaging sources such as Microsoft Teams chat, WhatsApp and the myriad other platforms that may now be in use by your hybrid workforce.
