About API get list events in Calendar View getting All-day event

Occasional Visitor

Hello there,


I have a question. Can anybody here show me the exact changelog for the Rest API list calendarView. I think there're some changes that I haven't catched.


For example. when I called this API last year, if there's an all-day event in 2020-12-28 and I set startDateTime 2020-12-29T00:00:00, that event wouldn't appear on the response.


But now, I create an all-day event in 2020-12-28. When I call this API and set startDateTime 2020-12-29T00:00:00, I'm still able to see this event on the response. Only when I call this API and set startDateTime 2020-12-29T00:00:01, I could not see this event anymore. (Screenshots below)









I'm sorry if my explanation for my problem is hard to understand.


Thank you for reading, any help would be appreciated.

Did you ever receive an answer on this or find out what you needed?

Best, Chris

Thanks for reaching out, we are checking this internally and get back to you asap.



We are not able to reproduce the issue, we are able to receive the response in both(creating a ll day event and updating) the cases. Tried in graph explorer and in Postman as well.


Created all day event on 2021-01-29 and able to see the update in calendar and received the response. And changed the startDateTime to 2021-01-29T00:01:00.0000000 , able to receive the response.

Could you please try again and check are you still facing the issue?
