Microsoft announced the end of mainstream support for its Exchange Server 2019 on-premises mail server software on January 9, 2023.
"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," said Microsoft Exchange Product Marketing Manager Scott Schnoll on Monday.
Even though Microsoft hasn't provided Exchange 2019 end-of-life guidance and has yet to release a new on-premises Exchange Server version, Schnoll said on Monday that Redmon will soon share more details on what's coming next.
Exchange Server 2016 is also under extended support until October 2025, after reaching its mainstream end date in October 2020.
Admins are advised to switch to Exchange 2019 to keep receiving updates for new security flaws or migrate to Microsoft's hosted Exchange Online.
