Tag: Exchange Server Subscription Edition

Microsoft plans a transition of the current Exchange Server licensing and support model to Exchange Server subscription edition (SE) starting in 2025. Organizations must prepare for the transition by upgrading servers to the latest cumulative updates of Exchange 2016 and Exchange 2019. The transition is unlikely to be seamless, but glitches can be avoided by good planning and careful monitoring of community discussions.

Microsoft has announced that Exchange Server Subscription Edition (SE) will appear in summer 2025. You'll be able to do an inplace upgrade from Exchange Server 2019 CU15 or a "legacy upgrade" (hardware switchover) for other versions. The initial version of Exchange Server SE is unexciting, perhaps deliberately so. It's all about getting customers to transition to the subscription model.
