Is there a way to set your normal non-working hours (e.g., 5 PM to 8 AM) so
that if somebody attempts to schedule a meeting during this time, they are
informed that you are unavailable? The Tools-Options-Calendar Options
window allows you to set a standard "Start time" and "End time", however,
this only appears to change the background color for those hours on your
calendar and is not visible to other users.
