 Title: Microsoft 365 service health.

 Data source: Microsoft Graph {/admin/serviceAnnouncement/healthOverviews}.

 This check monitors the overall health status returned by Microsoft for each subscribed Microsoft 365 service. The raw Microsoft Graph status is retained in the Details output, while the Summary translates values such as {serviceDegradation} and {serviceInterruption} into operator-friendly text.

 Default state mapping: {serviceOperational}, {serviceRestored}, {postIncidentReviewPublished}, {falsePositive}, resolved and mitigated states are OK; {serviceDegradation}, investigating and recovery states are WARN; {serviceInterruption} is CRIT; an unknown/future status is UNKNOWN. The mapping is configurable with the "Microsoft 365 service health states" rule.
