Exchange SE - forest functional level
According to this:
https://learn.microsoft.com/en-us/exchange/plan-and-deploy/supportability-matrix
Exchange SE doesn't yet support the Server 2025 functional level. Is there any indication of when this will arrive? With CU1?
Thanks

It's true that Exchange Server SE does not support the Windows Server 2025 FFL, but even if it did, it would not provide any specific benefits for Exchange. AFAIK, CU1 will not introduce support for Windows Server 2025 FFL.
Your Domain Functional Level (DFL) can be Windows Server 2025, though.
Out of curiosity, do you have other applications that require a higher FFL? Or is there some other reason that Windows Server 2025 FFL interests you?We don't particularly need the higher FFL, but in the past I've normally moved up to newer versions once our infrastructure supports it - which it now does, except for Exchange FE.
I'm not going to risk breaking the Exchange server, so I'll wait until the 2025 FFL is officially supported before making any changes.
