M365 Service Health - Live Microsoft 365 Service Health in Copilot Chat

M365 Service Health is a SharePoint Copilot App built as an SPFx 1.24 Copilot Component. Its declarative agent answers service availability questions by rendering live Microsoft 365 service health data from the Microsoft Graph service health API directly in the Copilot conversation.

The React component supports inline and full-screen display modes, service search, active-issue filtering, natural-language service name resolution, and issue details with impact and status updates. It also demonstrates brokered Microsoft Graph access, retry with exponential backoff, classified error handling, host-driven theming, and graceful degradation.
