Hi Cristian,

Thanks for reaching out!

Forbidden error occurs when the user might not have enough permissions or might not have a required license.

I can understand that you are trying to Update the calendar; to update the calendar, you need to consent to the "Calendars.ReadWrite" for user calendar for both delegated and application permissions.

Hope this helps.
