Can I stop "Resources" from sending email accepting appointments?

Our receptionist will schedule an appointment on a calendar that somebody has shared with her. She selects the location which is a resource "conference" The resource is set to auto-accept appointments unless busy.

For every appointment the receptionist makes for a shared calender, the resource sends her an email accepting the apppointment.

The email says it is
sent by
attachments meeting.ics

The body of the email

conference has been scheduled for your appointment.
