Microsoft has baked a new threat mitigation feature into Exchange Server that will roll out this week as part of its September 2021 cumulative update to the software platform.

The new Emergency Mitigation (EM) software component allows Microsoft to create and execute vulnerability mitigations for its customers' Exchange Servers automatically. The EM service checks for mitigations hourly via Microsoft's cloud-based Office Config Service.

"If Microsoft learns about a security threat and we create a mitigation for the issue, that mitigation can be sent directly to the Exchange server, which would automatically implement the pre-configured settings," the Microsoft Exchange Server team wrote in a community blog post announcing the new feature.

Microsoft: New security feature in September 2021 Cumulative Update for Exchange Server

Security is a top priority for Microsoft and our customers, and we continue to work very hard to keep customer data secure from cyber-threats, while ensuring compliance with evolving regulations. As part of our continued work to help you protect your Exchange Servers, in the September 2021 Cumulative Update (CU) we have added a new feature called the Microsoft Exchange Emergency Mitigation service.

This new service is not a replacement for installing Exchange Server Security Updates (SUs), but it is the fastest and easiest way to mitigate the highest risks to Internet-connected, on-premises Exchange servers prior to installing applicable SUs.
