    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.

    Document reference: https://learn.microsoft.com/en-us/graph/api/calendar-update?view=graph-rest-1.0&tabs=http#permissions

    Hope this helps.
