Missing event from user (calendar graph api)

Question

Hi,

I'm here today because after trying for hours to get some missing events on graph api,

I wasn't able to find any reason but some events are not in user's calendar,

I'm listing the users in my organizaton, and looping over them and calling "list events" on each user

https://learn.microsoft.com/en-us/graph/api/user-list-events?view=graph-rest-1.0&tabs=http
(GET /users/{id | userPrincipalName}/events)

Yet for no reason some events are missing and I found no reason why this behavior is happenning,

Could you help me to find for which reason this issue is happening to me ?

Thanks you !

• I am not aware of any restrictions with the API or per tenant per se.

• Just to isolate the issue outside of your code, try the same tenant in Graph Explorer/POSTMAN, test the same API call and observe the results.

• In addition, you can setup/subscribe the change notifications and you will get the related change notifications for the given events as well
