working for different companies. I am able to publish the information to a
shared internet location, but it does not retreive the information when
creating a new appointment.

settings a

Free/Busy options
publish at my location:
http://myserver/calendar/myname.vfb (= microsoft IIS server)

Search location:
http://myserver/calendar/%NAME%.vfb

I have also included the search location in the contact's detail window

Any suggestions on how to get it fixed?
