Hot Take:

Well, folks, it looks like Microsoft has decided to throw a farewell party for Exchange Server 2016 and 2019. The catch? No one wants to attend because it means more work for IT admins. But hey, upgrading is just a glorified reason to pop open some virtual champagne and celebrate the never-ending cycle of technology updates, right? Cheers to security patches and endless migrations!

Key Points:

  • Microsoft has officially ended support for Exchange Server 2016 and 2019 as of October 14, 2025.
  • Admins are advised to upgrade to Exchange Server SE or migrate to Exchange Online.
  • Continuing to use outdated servers post-support invites security vulnerabilities.
  • In-place upgrades from Exchange 2019 to Exchange Server SE are possible.
  • Windows 10 has also reached its end of support.
