Are you interested in learning more about Microsoft Exchange Edition and how it can modernize your email infrastructure? If yes, then this post is for you!


What is Exchange Subscription Edition?

Microsoft Exchange has long been a cornerstone in the world of enterprise email solutions, providing robust and secure communication infrastructures for businesses worldwide. As technology continues to evolve, so does Microsoft’s flagship email server. The upcoming changes (early Q3 2025) to On-premises Microsoft Exchange and the introduction of the new Exchange Subscription Edition (SE) represent a significant shift, promising enhanced functionality, security, and flexibility for organizations of all sizes.

As cloud solutions have become increasingly dominant due to their scalability and cost-effectiveness, many organizations are required to maintain on-premises infrastructure due to regulatory requirements, security concerns, or specific operational needs. Exchange SE is tailored to meet the needs of these businesses, ensuring they can leverage the latest technological advancements while maintaining their preferred operational model.

Microsoft will end support for Exchange 2019 and 2016 in October 2025, requiring organizations to upgrade. Microsoft has clarified that the Exchange SE will carry forward many of the features found in Exchange 2019 CU15 while adopting a subscription-based licensing model. This means that at launch Exchange SE features will closely mirror those of Exchange 2019 CU15, offering businesses an updated and streamlined method to manage their email infrastructure.


The Move to Subscription-Based Licensing

One of the most notable changes with Exchange SE is the shift from traditional perpetual licensing to a subscription-based model. For you, this will mean predictable, regular payments rather than a large, one-time expenses. More importantly, it ensures that users always have access to the latest updates and features to enhance their email infrastructure.


System Requirements and Compatibility

Before installing Exchange SE, it is important to note that Exchange 2013 must be completely removed from your organization prior to installing Exchange SE. This requirement ensures that there are no compatibility issues and that your new email infrastructure runs smoothly. Additionally, Exchange SE supports several operating system versions, including Windows Server 2019 and Windows Server 2022. Exchange SE will also be supported on Windows Server 2025. Ensuring your operating system is compatible is a critical step in preparing for the migration.


Transitioning to Exchange SE

Microsoft has outlined a clear migration path designed to minimize disruption and ensure a smooth transition, however decommissioning older versions of Exchange may involve some potential impacts. With any migration, you should be prepared for possible downtime, especially during critical phases of the transition. Planning for these periods is vital to minimize operational disruptions. Additionally, the specifics of data migration need careful consideration. Ensuring that all data is securely transferred to the new system without loss or corruption is a key aspect of the migration strategy. This involves detailed planning and execution to ensure data integrity and continuity of service.

You can work with Microsoft or certified partners to plan and execute your migration, taking advantage of tools and resources designed to facilitate the process.


In-place upgrade from Exchange 2019 to SE

If you are currently running Exchange 2019 and the latest CU updates, an in-place upgrade offers a quick and easy path to modernize their email infrastructure. This upgrade allows for the retention of existing settings and configurations, significantly reducing the time and effort required compared to a full migration.

Planning the Migration

Effective planning is critical for a successful migration to Exchange SE. Businesses should conduct a thorough assessment of their current email infrastructure, identifying any potential challenges and opportunities for improvement. This assessment should include an evaluation of hardware and software requirements, as well as an analysis of current email usage patterns. Additionally, it’s important to note that Exchange SE will not coexist with Exchange 2013, meaning Exchange 2013 must be completely removed before installing Exchange SE. Moreover, after Exchange SE CU1, it will also not coexist with Exchange 2016 or Exchange 2019. By understanding your existing environment and accounting for these requirements, you can develop a comprehensive migration strategy that addresses your unique needs.

Execution and Support

Once the migration plan is in place, you can begin the process of transitioning to Exchange Subscription Edition. Microsoft provides a range of tools and resources to support this transition, including detailed documentation, migration guides, and support from certified partners. Additionally, your business can take advantage of Microsoft’s support services to address any issues that arise during the migration process.
