Email Archive Migration

Consolidate your ecosystem under a single, secure and compliant roof.

Microsoft continues to raise the bar on email security and compliance. That makes it harder and harder to justify the additional costs and complexities of third-party email archiving solutions.
Breaking free of these often intentionally locked-in platforms may not be easy, but the rewards are significant. We’re here to smooth your email archive migration journey and make sure you enjoy all the cost, functionality and security benefits of a unified Microsoft estate.

Your needs

Email is the lifeblood of your organisation. You need it to function as an integrated part of your technology ecosystem, playing by the same security and governance rules as everything else.

You’re likely already paying for cutting-edge email security and compliance features as part of your existing Microsoft subscription. It’s time to take advantage of those to unify your ecosystem and stop duplicating efforts. Consolidate your admin, reduce your overheads, increase productivity, and improve security and compliance coverage and response times. Say goodbye to data siloes and bring your email home.

Our solution​

As Gold certified Microsoft partners with decades of migration experience, getting your email data out of third-party solutions and into your Microsoft environment is all in a day’s work. What sets us apart is our commitment to achieving more than just a successful migration.

Our goal is to help you fully leverage the functionality available within Microsoft to not just replicate, but improve on the email archiving capabilities you had before. Together, we’ll help you achieve a secure, compliant and consolidated environment, and lay the foundations you need to take advantage of future innovations.

Our favourite challenges

Embracing Microsoft cloud for email retention requires a mind shift from the old days of traditional archives. Especially if you’re fully embracing Microsoft 365 security features.

As you transition from your third party solution we can help you with:

  • Legacy email with no logical home in Office 365
  • Surfacing legacy content for eDiscovery
  • Clearing out the ROT (redundant, outdated, trivial)
  • Aligning with retention and compliance
  • Establishing ownership of emails (senders/recipients)
  • Transferring from third party security features to native Microsoft 365

From Our Clients

The Cloud Essentials’ team have shown they are a partner, not just a supplier. The company we acquired advised that the IT integration project was the most successful part of their conversion to join us, which is a reflection on everyone involved. Thank you!

Head of Infrastructure

Job well done! I appreciate your knowledge, expertise, and teamwork/engagement which contributed to a successful migration/cutover.


"Cloud Essentials performed a mail migration for our Institute of Astronomy, from a legacy Microsoft Exchange server to the University Microsoft 365 Tenancy. Cloud Essentials were extremely professional from start to finish. They understood our Higher Education context. They were very flexible when setting the timeline when we had some challenges in our availability to support the work. Their staff were helpful and friendly. They demonstrated great expertise and guided us throughout the process. The migration itself was smooth and fast. Great service by a great team! I would recommend and use their services again."

Higher Education Institution

Project Manager

“This has been very refreshing. And Cloud Essentials have been not just an implementer, but a trusted partner. They’ve effectively become our ‘SharePoint arm’ within the company. They haven’t taken a cookie-cutter approach with something from another environment, but have genuinely wanted to find the best way to help us.”

CIO, Prominent law firm

Colin Short

"Cloud Essentials carried out a very professional service. They stayed cool, calm and collected. I’m sure it won’t be the last time we work with Cloud Essentials."

Global chemical company


It is no small achievement to reduce a corporate enterprise data footprint this significantly in a responsible, well planned and executed manner.

Information Manager, Alexander Forbes

Pierre Blignaut

“Cloud Essentials understand the importance of carrying out a project the right way, no matter the size of it. They don’t take any short cuts.”

Tenant Migration client

“This was a smooth migration with very little impact on the business during the changeover, we would definitely use Cloud Essentials and the Binary Tree toolset again if we need to do another migration!”
