Recurrent Events with Microsoft Graph

Hi

I have a problem with the Graph API regarding recurring events ( /me/calendars/<calendar_id> ).

My query is: /me/calendars/<calendar_id>/events?$filter=start/dateTime+ge+'2022-03-05T09:24:03+00:00'+and+end/dateTime+le+'2022-05-05T09:24:03+00:00'

Some recurrent events do not show up in the API. I can see them on Outlook but they are not present in the events returned by the API.

Do you know of any peculiarity that could explain this problem?

    Hi @Jérémie Darault

    Hope you are doing well.

    I’m unable to reproduce this issue using my test tenant. I am getting all the recurring events 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.

    Moreover, you can use List Instances API to get the instances (occurrences) of an event for a specified date range.

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

    I haven't seen this detail in the response and that's why i didn't get all my events. It works now !
    Thank you so much @HarmeetSingh7172 !

    I was having the same issue. I fixed mine by changing the url to /users/the@email.com/calendarView?select=subject... and so on. It has to include a startDateTime and endDateTime.
