Official Outlook Calendar route (Microsoft Work IQ)

Microsoft publishes official MCP servers (Work IQ) for Microsoft 365. Whether you can use them depends on your Microsoft 365 licensing. The server endpoint is tenant-scoped, so we can't live-check it from outside.

Endpoint: https://agent365.svc.cloud.microsoft/agents/tenants/{tenant_id}/servers/mcp_CalendarTools
In the official MCP Registry: Yes, com.microsoft/workiq-calendartools.

We don't claim these servers work in ChatGPT or Claude until Microsoft's docs say so. The community servers below are third-party.
