Microsoft have announced a set of important dates for end of support for both Exchange 2016 and Exchange 2019, during 2025. The new version of Microsoft Exchange, called Microsoft Exchange SE (Subscription Edition) is being released as RTM, and then as CU1.
All existing customers of Microsoft Exchange are expected to use solely Exchange Online, or to transition off Exchange 2016/2019 onto Exchange SE, in order to remain in Microsoft Support.

Download Exchange 2019 SE
We expect to cover information on how to download Exchange SE RTM as soon as it is available. And will be posting a detailed Blog entry on Exchange SE lab test right here as soon as we can.
Plan to Migrate to Exchange 2019 SE
Any organization using Exchange 2013, 2016, or 2019 should be planning right now on how they can migrate to Exchange SE. Right now it is recommended to be on Exchange 2019 CU14 with the latest Security Updates. And then move to Exchange 2019 CU15 when it is released. Move off any legacy Exchange 2013 or Exchange 2016 servers quickly.
Otherwise your legacy Exchange Servers will become out of Microsoft Support during 2025 H2.
Exchange SE will be the equivalent of a Cumulative Update (CU) following Exchange 2019 CU15.
Recap
In summary, you need to be aware that Exchange 2016 and Exchange 2019 are coming to end of support from Microsoft in 2025. Plan ahead and reach out for help on how to migrate to Exchange 2019 SE, which is the new version being released.
