Microsoft has sounded the alarm: Exchange 2016 and Exchange 2019 are reaching the end of support on October 14, 2025. Without security patches, these servers will be exposed to attacks. Admins, it’s time to embrace Exchange Server SE or migrate to Exchange Online. Don’t let your servers turn into sitting ducks!

Hot Take:
Microsoft is essentially telling us to move on from Exchange 2016 and 2019 because they are about to become the cybersecurity equivalent of a cheese left out in the sun. It’s time to pack those bags, upgrade, and say goodbye to servers that are about to become as useful as a chocolate teapot.
