I have a set of calendars within a public folder which people add

of telling O2k3 that they should not conflict with each other - if
someone has booked first then tuff titty?

See if something here helps:

I was more looking for a way to do it in Outlook, or to perhaps
implement the calendars better? These are meeting room bookings, and
am using public folders currently. I had a look on the site, but
currently want to restrict to using just Outlook with a backend
Exchange or have a simple script that does it.

Thanks.
