I am using EA version 2.3.11. We've added a custom field for adviser notes for workers to comment on an appointment. When the appointment is edited and then saved an email notification is sent out by default.  I am not able to turn this off. If I uncheck the "Send email notification" checkbox, the email is sent regardless.  I have not found any setting that can override the default. I want to be able to control when an email notification is sent when I edit an appointment.
