This provides a unified view of all events from every calendar, supporting timezone preferences and OData query parameters for filtering, sorting, and pagination. Complements the specific calendar LIST_EVENTS function. - List calendar view (`MICROSOFT_CALENDAR__LIST_CALENDAR_VIEW`): Get events, occurrences, exceptions and single instances from a calendar within a specified time range. This returns actual calendar events/appointments between the start and end dates. - List calendars (`MICROSOFT_CALENDAR__LIST_CALENDARS`): Get all the user's calendars. This retrieves calendars from the default calendar group and allows filtering, sorting, and selecting specific properties using OData query parameters. - List events (`MICROSOFT_CALENDAR__LIST_EVENTS`): Retrieve a list of all events in a calendar without date restrictions. This returns single instance meetings, series masters, and recurring events. Use this to get all events in a calendar regardless of time range. - List instances (`MICROSOFT_CALENDAR__LIST_INSTANCES`): Get the instances (occurrences) of an event for a specified time range. If the event is a seriesMaster, returns the occurrences and exceptions in the range. - Create calendar (`MICROSOFT_CALENDAR__CREATE_CALENDAR`): Create a new calendar for the user. This creates a calendar in the user's default calendar group with the specified name and optional properties like color. - Create event (`MICROSOFT_CALENDAR__CREATE_EVENT`): Create a new event in a calendar. This allows creating meetings, appointments, and events with attendees, locations, recurrence patterns, and online meeting details. - Create event default (`MICROSOFT_CALENDAR__CREATE_EVENT_DEFAULT`): Create an event in the user's default calendar with simplified parameters. Perfect for quick event creation without specifying a calendar ID. Supports all event features including attendees, locations, recurrence patterns, and online meeting details. - Get calendar (`MICROSOFT_CALENDAR__GET_CALENDAR`): Get the properties and relationships of a specific calendar object by its ID. This retrieves detailed information about a calendar including permissions, settings, and metadata. - Get event (`MICROSOFT_CALENDAR__GET_EVENT`): Get the properties and relationships of a specific event.

Supports timezone preferences and custom property selection. - Get schedule (`MICROSOFT_CALENDAR__GET_SCHEDULE`): Get the free/busy availability information for a collection of users, distribution lists, or resources (rooms or equipment) for a specified time period. Perfect for finding available meeting times and checking when people are free. - Delete calendar (`MICROSOFT_CALENDAR__DELETE_CALENDAR`): Delete a calendar other than the default calendar. This permanently removes the calendar and all its events. The default calendar cannot be deleted. - Delete event (`MICROSOFT_CALENDAR__DELETE_EVENT`): Delete a specific event from the calendar. If the event is a meeting, deleting it on the organizer's calendar sends a cancellation message to all attendees. This action cannot be undone. - Update calendar (`MICROSOFT_CALENDAR__UPDATE_CALENDAR`): Update the properties of an existing calendar object. You can modify the calendar name, color theme, or default calendar status. Only include properties you want to update. - Update event (`MICROSOFT_CALENDAR__UPDATE_EVENT`): Update the properties of an existing event.

Supports delta query for incremental sync. - Dismiss reminder (`MICROSOFT_CALENDAR__DISMISS_REMINDER`): Dismiss a reminder that has been triggered for an event in a user calendar. - Forward event (`MICROSOFT_CALENDAR__FORWARD_EVENT`): Forward a meeting event to new recipients.

The new recipients will be added to the event and notified. - Permanent delete event (`MICROSOFT_CALENDAR__PERMANENT_DELETE_EVENT`): Permanently delete an event and place it in the purges folder in the dumpster.
