Microsoft’s Exchange Server SE: The Eternal Email Solution or Just Another Subscription?
Microsoft announces Exchange Server Subscription Edition, an “evergreen” release with no expiration date. While it mirrors Exchange 2019 CU15 for now, expect future updates. As Exchange 2016 and 2019 end support in October, Exchange SE will be the last on-premises version, paving the way for a streamlined email experience.

Hot Take:
Ah, Microsoft, the maestro of keeping us on our tippy toes! Exchange Server SE is officially here, and just like that one annoying buzzword at every corporate meeting, it’s going to be around forever—or at least until someone decides otherwise. Welcome to the ‘forever young’ edition of your email server!
Key Points:
- Microsoft has unleashed the Exchange Server Subscription Edition (SE) upon the world.
- The SE version can be installed on servers running Exchange Server 2019 CU15 or CU14.
- Exchange Server SE is governed by the Modern Lifecycle Policy, meaning it has no fixed end date.
- Exchange 2016 and 2019 will reach the end of support in October 2025.
- Exchange SE will be the only supported on-premises version after the end of support for older versions.
