Key benefits migrating your email archives to Office 365 with us.

With over 300 migrations and 20 years’ experience in archiving, you can be assured your email archives are in safe hands with Essential as you migrate to Office 365.

Even if you don't have a regulatory need to protect your records, ensuring staff retain quick and easy access to past business transactions and other information held in emails can have a massive impact on business efficiency and your bottom line.

To deliver your migration we have partnered with the world-leaders in archive migrations, TransVault, authors of the first product to be certified by both Microsoft and Veritas (Symantec), and whose technology is proven in over 2,000 projects the world over.

Here are some of the reasons why a TransVault-powered migration is regarded so highly:

Super Fast

High-speed connectors deliver the fastest yet safest archive extractions around and TransVault's CloudStream technology combines Microsoft best practices with expert algorithms to give you the fastest, 1-step migrations direct into Office 365.  There’s also the option to use Drive Shipping/Cloud-based uploads (but we don't think you'll need to).

User Aware

Sometimes legacy archives get 'out of synch' (or don't synch shortcuts at all).  This can lead to deleted items re-appearing or things being put in the wrong folders post-migration.

All this is taken care of, we also delete legacy shortcuts so they don't appear in Office 365.

This means no surprises, no confusion and no loss of productivity 'post migration'.


Advanced filtering lets you easily select what gets migrate and where. E.g.

  • Move selected departments/folders/users
  • Move items > 2 years to archive mailboxes
  • Migrate deleted items to the RIF

We can help you map existing policies into your Office 365 retention policies.


All data moved is fully audited and nothing slips through the net...

  • Detailed chain-of-custody reports
  • At a glance migration status updates
  • Auto-retries of any failed items
  • Inbuilt trouble shooting & online KB


TransVault was the first migration vendor to be certified by both Symantec and Microsoft.

IT'S ALSO PROVEN IN 2000+ PROJECTS to give you and your customer the ultimate peace of mind.

"The product had enough flexibility to handle our specific requirements and get us the speeds we were looking for in terms of throughput to Office 365. I would not hesitate in recommending this software, and indeed, Essential, as a service delivery partner, to anyone asked."

 - Ian Gates, Director of Group IT, Capita
