I am having an issue under scheduling within Outlook. We are running an Exchange 2003 server. It was a clean install, not upgrade from 5.5. Anyways, under scheduling, when i add attendees I have a single attendee where I get the error, No Information, No Free/Busy Information could be retrieved. All other attendees though show up and show me there information. What would cause the one attendee to not show up and what do I need to do to fix it. Any help would be greatly appreciated.
