I set up a public calendar folder for a conference room so that the room can
be scheduled via Outlook. This is on Exchange 2000 as part of SBS2K server.

However, since this is a public folder only (no user associated), users must
schedule events & invite attendees from the Conference Room folder (i.e. not
their own calendar), and responses are not tallied.

How can I set up this resource as an entity that can be scheduled by
invitation as an attendee so that users can schedule it from their own
calendars and receive responses from other attendees?
