share outlook 2000 subfolders

Is there a way to look at another users subfolders of say the inbox? Currently we have the user's outlook info to be shared on our exchange server, and I can see the inbox, but not the subfolders of the inbox when I set permissions on outlook and then go to open other users folder. IS there a way to see the subfolders? We are running outlook 2000 and have ms exchange 5.5 sp4.
