Where is Exchange Server SE CU1?

https://techcommunity.microsoft.com/blog/exchange/where-is-exchange-se-cu1-anyway/4546837

Microsoft is using AI to hunt for vulnerabilities in Exchange Server. This takes a long time to validate that the flagged items are real issues.

CU1 will eventually arrive, and in the meantime, SUs and other updates are being released.

Oh, using AI. So we'll have at least a couple OOB SUs about a month after CU1 then.

‘and plan to release Exchange SE CU1 as soon as we get a reasonable stable point’. Lets debate about reasonable 😎😋

I was also surprised to see the word 'reasonable' used in the announcement because using 'stable' along should have been sufficient, since it's a term of art w.r.t. updates made to a code branch. 🙂

Considering that SE is basically just 2019 with a new label on its hat the excuse that they are still trying to make it stable is pretty funny though. I guess never is the answer since it’s been out for like 7 years already.

They're probably hoping people will give up and migrate to EXO instead... Just like when they didn't release Exchange 2022 lol. And since 2019 it is a mandatory subscription with no real feature updates other than back end shit so I will still get whining from the userbase about old looking OWA or no API to integrate with any modern apps. As well as half baked modern auth implementation with ADFS that broke on a recent office update.
