I'm in the process of scheduling training sessions for a new technology
setup in one of our conference rooms. Unfortunately, I can only
accomodate 5 or 6 people at a time.

I'd like to send out an invitation to the meeting to everyone in the
office (about 70 people) but only have outlook accept the first 5 or 6
people who accept the meeting. Is such a thing possible?

I'd basically like to send out a large number of invitations, but only
accept a small number of attendees.

Any thoughts?
