Unable to get calendar events using Microsoft graph: 403 error access denied

Question

I am making calls to the Microsoft Graph "/users/{id}/events" endpoint as an apllication with no logged in user but getting 403 forbidden
"error": {
"code": "ErrorAccessDenied",
"message": "Access is denied. Check credentials and try again."
}
}

I have encountered this error and got stuck, I am accessing user/{email}/events. I have already granted all the Application permissions but still the error occurs.
How do I resolve this issue in MS Graph?

Hello Stephen Gray,

Thanks for reaching out.

Try removing & revoking all Calendar related permissions of the application and grant only the required (or least privileged) application permissions to execute List Events Graph API [Calendar.Read].

Hi @Stephen Gray , you can decode your access token in jwt.ms to ensure that the token contains the correct permissions. You can also share it in the comments so that we can help you analyze together.

Best Wishes.
