A: It depends on whether the host has a calendar sync enabled. The host is the user who booked the appointment.
- If the host has no calendar sync enabled, open the appointment and remove yourself from Participants. This works as long as your access rights let you edit appointments.
- If the host has a calendar sync enabled, only the host and administrators can edit the appointment. Other users see the message "You can't edit this appointment since you're not the host and the host has a calendar sync enabled." You can still leave notes, create follow-ups and upload files. Ask the host or an administrator to remove you.
