Sun Java System Calendar Express Help

I've set up an appointment on Calendar Express and when I look at the calendar of the room I've set the appointment in, it's not there. I can see the appointment in my own calendar (both Outlook 2003 and Calendar Express), but not in the calendar of the location of the meeting (until about 24-48 hours later). Can somebody please help me figure out why meetings aren't being posted until a day or two after the initial setup?
