Calendar Inconvience

When an event is cancelled, the event should be deleted automatically from the summary view of the calendar. The way it is set up, you have to click on the event to see that it was cancelled (there is an email notification, but people who may not have checked their email would not be aware of the cancellation).

I deleted the a specific date mtg., and it is still showing on the calendar.

any insight or wisdom would be great! Thanks!
