Outook 2000

I created a Resources account from Outlook 2000. Under the Calendar of that account I created a few separated calendar folders for out different conference rooms so certain people can shcedule meetings themselves ( setup the way only certain people have rights). When they login to their Outlook account, go to File, Open Other’s Folder and specify name and folder which is Calendar they only see one major Calendar and Folder list is not available to be able to see other calendars folders. Is there anything I did wrong? Please help me! Sorry to bug you all!
