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 costly.
- You may decide that you don’t want to ‘put all your eggs in one basket’ by migrating journals into Microsoft 365.
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.
