Normally, these mitigations are implemented by a Security Administrator but Microsoft offers this service to automatically configure and enforce these mitigations. The Exchange Emergency Mitigation Service helps you to mitigate vulnerabilities on your server and secure it as much as possible from any known vulnerabilities.

To help you secure your Exchange Servers from such threats, Microsoft offers the Exchange Emergency Mitigation (EM) Service. So, you need to make sure that your Exchange Servers are locked down and secure, especially when the Exchange Server connects to the internet for incoming and outgoing messages. Although you might have the latest Exchange version and all the Cumulative Updates (CU) installed, your Exchange Server might still be at risk of some potential threats in the wild.
