Disable Reschedule Broken
The ability to disable the reschedule feature for the person receiving the invite seems to be broken. I deselected the radio button (seen in my screenshot) in the service and saved changes. But when I test it, the email notification still provides me the ability to reschedule or cancel the appointment. In our organization, these appointments are time sensitive and legally cannot happen after a certain date, which varies for each person. We are managing over 200 appts per week, so it is not possible to do any sort of manual work around to ensure we catch unauthorized movement. In researching the issue, it looks like others have asked about the broken functionality, as seen in this 2024 post: Problem with the option to prevent customers managing their bookings | Microsoft Community Hub. But there has been no response. How do we get this issue on Microsoft's radar?
