Today marks the end of Mainstream support for Exchange Server 2019. Per the Exchange Server 2019 lifecycle, Exchange Server 2019 is now in Extended support. But, as we said last November, a lot more is coming for Exchange Server 2019. There are still two more CUs for Exchange Server 2019: CU14 and CU15. CU14 is in its final stages of testing and validation and will be released as soon as that's finished. CU15 will be released later this year.
As for what comes next, we'll be sharing those details soon, so stay tuned!
