Offline Folders & Network Public Share

I have multiple users that connect and update data on a network share. A

number of these users use laptops with Windows XP and setup offline folders

on the network share so they can access the data when they're offline. The

issue at hand is that other users in the office that also have access to

that public share will add folders and data to the share but the laptop

users with offline folders don't synchronize other users created folders or

files. Is there a way to get the offline folders to synchonize other users

added files and folders?

Thanks for any assistance,

Dan
