Attendees receive a meeting update after the event reminder is triggered

After the reminder for an event is triggered, attendees receive a meeting update without any changes. Additionally, attendees receive a meeting request in their Inbox that includes the No Response Required option.
The organizer of the meeting performed an action on his or her iOS 9.x device that sent a change for the appointment to Exchange. A new behavior was introduced in version 16 of the Exchange ActiveSync (EAS) protocol in which Exchange sends meeting updates when an EAS client sends a change for the appointment.
