[SOLVED] I'd like to cancel a single event from recurring events using the Microsoft Graph API

I'd like to cancel a single event from recurring events using the Microsoft Graph API

I have created a recurring event from December 3rd to 6th using the graph API, which repeats daily. I'd like to cancel a single event on December 4th. How can I achieve this? I fetched the event ID for the particular day. If I cancel an event using the event ID, all the events will be removed from the Outlook calendar. I don't want that. I want to remove only certain events from the Outlook calendar.

This is one of the event responses.

        }

I tried to cancel a single event using ID. All events are removing from the calendar.

Solution

Find the instances using following API

GET /me/events/{id}/instances?startDateTime={start_datetime}&endDateTime={end_datetime}

then take the occurrence (instance id)

delete the specific occurence (instance)

 DELETE  - https://graph.microsoft.com/v1.0/me/events/{instance-id}
