The EXOSrvcHlhTest test helps administrators with this! This test reports the status of the Exchange Online service in real-time, thus proactively alerting administrators to a service degradation. The test additionally reveals if any service incidents are occurring, and elaborately describes such incidents vide detailed diagnostics. If Exchange Online has been stopped as part of a planned maintenance activity, then this test indicates the same by reporting the count of maintenance events associated with Exchange Online.
