How can i get all the instances of recurring series event its returning only 10 instances not all

Question

now I want to get all the list of instances within the specified date range and for that, I used this graph API

Here eventId is the master event id of the recurring series

https://graph.microsoft.com/v1.0/users/{userId}/events/{eventId}/instances?startDateTime=2022-09-19T00:00:00&endDateTime=2022-11-30T23:59:59

But it returns only the first 10 instances not all, what I am missing here.

Hi @praveen j ,

Hope you're doing well.

I’m unable to reproduce this issue using my test tenant. I am getting all the occurences (instances) for an event in graph API response.

There is a possibility you might be checking the first page only. The Calendar API has a default page size of 10. You can use “@odata.nextLink” property to obtain all results. The page results is not sorted by start date unless “OrderBy” is specifically added.

Refer below screenshots for better understanding-

Hope this helps.
