OUTLOOK AUTOMATION

I want to create meetings in Outlook using Access 97. I can create the meeting with no problem, However I cant figure out how to check for conflicts using code. I can leave the user at the meeting window and let them check on the attendees availabilty but that defeats the whole purpose.At worst I’ll like to leave the user at the Meeting window with the Attendee Availability screen showing.

I want to either have a message come back telling me that there is a conflict or to leave the user at the Attendee Availability Window.
