I am responsible for setting up meetings for our team, we don't have Exchange
just do everything via email. Also, our team uses Blackberrys for on the
road so I need to make sure the computer calendar matches up with the
Blackberry calendar.

It has come to my attention that when I change a meeting to a different day,
the original meeting doesn't go away. It changes on my own calendar so I'm
not sure what the recipients are doing or not doing.

Also, when I cancel meetings, do the recipients need to open the email and
accept the cancellation and have it remove from the calendar for it to
completely go away?
