Exchange Server Subscription Edition (SE) was released for general availability on July 1, 2025. This release continues Microsoft’s commitment to supporting enterprise email services across cloud, on-premises, and hybrid environments.
Exchange Server SE introduces changes to how Exchange is serviced and licensed. Unlike previous versions, Exchange SE is governed by the Modern Lifecycle Policy. This means there is no fixed end date for support, provided that configurations remain current. The product will be serviced continuously as an evergreen release, with no additional major, year-based versions planned for the future release.
Exchange Server SE RTM build can be installed as a cumulative update (CU) to Microsoft Exchange Server 2019 CU15 or CU14, and it can be joined to your existing Exchange Server 2019 or Exchange Server 2016 organizations.
For more information about the upgrade process, see Upgrading your organization from current versions to Exchange Server SE. ​​​​​​​
