Create Calendar Event

Published today

Create an event in the default calendar or a chosen one. `start` and `end` are local times in `time_zone` (`2026-01-15T14:00:00`); attendees receive an invitation. `recurrence` takes a Graph patternedRecurrence object, e.g. `{"pattern":{"type":"weekly","interval":1,"daysOfWeek":["monday"]},"range":{"type":"noEnd","startDate":"2026-01-19"}}`; `extra` takes any other event property. Requires Calendars.ReadWrite (a connection default).
