Exchange System Health Test

The Exchange System Health Test monitors health sets (groups of monitors) and health information on your Exchange 2013/2016 server, verifying the state of each health set’s monitors. Monitors that are similar or are related to a component’s architecture are grouped to form a health set. Health sets provide the health information for applications and services such as Outlook Web App, Exchange ActiveSync, the Information Store service, content indexing, and transport services on your Exchange 2013 and Exchange 2016 servers.

This test allows you to ensure the health state of health set (whether health or unhealthy).

You can run the system health test against Exchange 2013 and later.
