Using Outlook 2003. When using the scheduling tab, some users show up with diagonal lines representing "no information" while others free/busy information is available. I have set the free/busy parameter to publish 12 months of information to the server, and update every 15 minutes. Users have rebooted and their free/busy parameter shows as 12 months, but when you try to send them an appointment invite and use the scheduling tab, it doesn't show the information for them. Any ideas?
