  title: Microsoft Exchange Find Times and Book a Meeting
  summary: Suggest meeting times for attendees, then book the top suggestion.
  description: >-
    A scheduling-assistant pattern on Microsoft Graph calendar. The workflow
    asks Graph to suggest meeting times for a set of attendees within a time
    window, then books an event using the start and end of the highest-ranked
    suggestion. Each step inlines its request so the flow can be executed
    without consulting the underlying OpenAPI description.
