Exchange Server Subscription Edition Arrives in Summer 2025
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.

Tony, I'm also reading if you're on CU 14 that you can perform an Inplace upgrade to ESSE, is this correct?
My understanding is CU15. CU14 is now an old update (Feb 2024). Microsoft wants you to use the latest CU.
- THe question is, which first of January?
