Microsoft’s Warning: Outdated Exchange Servers at Risk of Cyber Attacks
Could your organization be vulnerable? Microsoft has confirmed that outdated Exchange servers will not receive new emergency mitigations, putting email security at risk. This decision stems from the deprecation of an essential certificate type, which affects servers running versions older than March 2023.
Importance of Keeping Exchange Servers Updated for Security
Keeping your Exchange servers updated is crucial for maintaining security and functionality. The Exchange Emergency Mitigation Service (EEMS) was designed to automatically apply interim mitigations for high-risk vulnerabilities. However, if your servers are outdated, you won’t benefit from these protections.

How to Check Your Exchange Server Status
Wondering how to verify if your Exchange server is up to date? Microsoft provides tools like the Exchange Server Health Checker, which can help you assess your server’s current status and necessary updates. Regular checks can prevent security issues before they arise.
