Email Journal Migration

Move your legacy Exchange journal & journal archives to a new platform.


Migrating Email Journals

If you need to move your existing email journal to Microsoft 365, you’ll face a number of challenges.

The biggest problem is that there is no equivalent in Office 365 to an Exchange journal mailbox.  By that we mean, the journal mailbox you may have been running in Exchange on-premises to date or in a service like Mimecast or Proofpoint.

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

  • You can’t simply migrate your journal into one or more Office 365 mailboxes as this can break Microsoft’s licencing rules.
  • Vital envelope metadata including any recipients that were BCC’d or part of a distribution list (DL) at the time the email was sent must be preserved to ensure accurate eDiscovery.
  • Your legal department will be keen to get a complete audit that proves every item has been successfully migrated and that chain-of-custody has been maintained.
  • 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.

Speak to the migration experts

Essential offers a range of services to enable you to preserve, migrate, and if required, keep running a journalling service for your essential email records.

We can also help you reduce the costs of migrating and maintaining an email journal.  For example, by hosting your journal in Microsoft Azure using a low cost, zero-lock-in subscription.

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

Journal Migration Choice

Discover your Best Journal Migration Options

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

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

We can help work out the optimal approach, and answer questions such as:

  • Can we reconstruct our journal archives into the right format a new archive?
  • Is it OK to move journals into one or more Microsoft 365 mailboxes without breaking licencing rules?
  • How can we ensure all the relevant metadata is preserved and discoverable post-migration?
  • Should we consider an alternative storage and eDiscovery platform for our journals?
  • What’s the best way to extract journals from services like Mimecast?
