Microsoft 365 Email Migration

A successful Microsoft 365 email migration requires collaboration, comprehensive planning, and thorough design work. We will analyse your existing platform, identifying potential improvements to make things better for your business once the migration has been completed successfully.

  • Cloud & On-Premise

    Whether migrating to Microsoft 365 or Microsoft Exchange on-premise, we make the transition as seamless as possible, stress-free for you.

  • Minimised Downtime

    The priority is your business and keeping downtime to a minimum is crucial. We keep you in the knowhow ensuring you and staff experience as little disruption as possible.

  • Onsite Aftercare

    When cutover takes place, we will be onsite ensuring staff have total support, making sure everyone is working correctly and any questions can be answered.

Email migration introduction

Moving to Microsoft 365

It is very important to keep up-to-date with all technology so you avoid being vulnerable to attacks or data breaches, and your email system is no different.

Microsoft Exchange 2016 extended support from Microsoft starts from 13th October 2020 until 14th January 2024. Microsoft Exchange 2019 extended support starts from the 9th January 2024 until 14th October 2025.

Microsoft 365 support never ends and is continuously updated – all covered in your subscription service with Microsoft.

Our Microsoft 365 Approach

  • Microsoft 365

    We can make your transition into a cloud-based Microsoft 365 platform seamless, providing you peace of mind and additional security going forwards. We plan cutover dates so that you know exactly what is happening and when to ensure your staff experience as little disruption in their working day as we can manage.

    Additional factors like decommissioning your old server, increasing availability, and improved backup capabilities are all benefits you could enjoy. Whilst we’d prefer to keep supporting your system afterwards, if you are looking for a one-off piece of work with minimal aftercare, then we can still help.

  • Your Business

    Microsoft 365 administration is a core capability for any MSP, and Geostream is no different. We handle all of your new user creations, leavers, and mailbox access requirements under IT support; tell us what you need, and we’ll keep you updated on the progress of your request.

    We know not every requirement is straightforward, so we aim to understand your teams and ensure that mailboxes are set up and how they will work most efficiently for your business. We deliver access to the right people when needed and on any device.

    Managing spam comes as standard, sometimes though emails slip through. We have security expertise to identify the source and advise you on the best steps going forwards, such as address or domain-specific blocks to protect your mail system further and reduce the risk to your employees.

We migrated to Office365. Downtime was very close to none at all! Chris & Bailey ensured this project ran smoothly. They were very easy to deal with. Our staff found them very responsive and very professional. Overall what could have been a very difficult and complex migration was completed successfully with no issues. Highly recommend.
