These are the permissione configured:

I'm getting Token correctly.

Then try these requests:

https://graph.microsoft.com/v1.0/users -> OK

https://graph.microsoft.com/v1.0/users?$filter=startswith(userPrincipalName,'l') -> OK

https://graph.microsoft.com/v1.0/users/{ID | Principal name}/calendars -> OK

https://graph.microsoft.com/v1.0/users/{ID | Principal name}/calendarView?startDateTime=2023-01-11T19:00:00-08:00&endDateTime=2023-01-21T19:00:00-08:00 -> ERROR

{
    "error": {
        "code": "ErrorAccessDenied",

Hi @Valter

Based on my observation from previous cases, I will suggest, try to remove & revoke all permission of the specific app and grant the required permissions again, then execute the Graph API.
Also, you can decode your token using JWT.IO and see in roles section if you have permission in your token.
Please let me know if you are still facing this issue.

Hope this helps.
