[SOLVED] Is it possible to get all events from all calendars regardless of calendar group

Is it possible to get all events from all calendars regardless of calendar group

I want to use a Graph request to pull all events from all calendars regardless of a calendar group. What I have tried:

GET /me/calendar/events
GET /me/calendarGroups/{id}/calendars/{id}/events

Case one I get from one calendar from the default calendar. case two I get from a specific calendar in any group. Any way of getting events from all calendars everywhere?

Solution

To get all events from all user's calendars you can use Client Credential flow which gives App only token and use it to query all calendars using below call

https://graph.microsoft.com/v1.0/users/userid/calendars

and then use the calendarid's and pull the events by using the below call for each calendar_id.

There is no direct call to get all events from all the calendars as of now. There is already a feature request raised in the Microsoft Graph Feature Request Forum, please upvote it so that it may be implemented in the future.
