Outlook 2003 can't see public calendar appointments

[Mike]

Here is the situation. We recently upgraded from exchange 5.5 to 2003
enterprise. Additionally, we are in the process of updgrading from office
2000 to office 2003. Now, here is the problem. In Outlook 2000, I can see a
public calendar's appointments. When I upgrade to 2003, I can no longer see
those appointments. Looking at the system manager for exchange, I can't see
the appointments either but, I know it has them because there are numerous
items in it (per the system manager).

Any ideas?
