The following scenarios are available when deleting events:
Deleting a Recurring Event: If the event you want to delete is a recurring event, a Confirm Delete Event window appears.

If you want to delete only the current instance, click Delete this one. If you want to delete all instances, click Delete All.
Deleting Appointments: If the event you are deleting is an appointment, you are asked for a confirmation before deleting the event. Subsequently, the appointment is deleted from the user's calendar.
Deleting Meetings: Depending on your role in the deleted meeting, the following actions are performed. If you are the organizer, a notification is sent to you informing that the event is deleted from the your (organizer's) calendar. For meetings, where you are an invitee, you are informed that the meeting is removed from your calendar and the organizer is informed that you have declined this meeting.
