Kolab2/Outlook2003 users shared calendars out of sync, any way to refresh them?

[John Dempsey]

Hi All,
Is there a way to refresh the calendar data on the server?
I'm testing between two users, and the shared calendars dont match up in the 
views between the two of them.  I had freebusy working earlier today, and now 
it seems that it's not getting the right data either.  Where is the actual 
calendar data kept on the server? Is it safe to delete it off the server and 
re-sync it?
Thanks
JD
