Propertiers folder on what? This is within Outlook 2k2 and has nothing to do with Exchange since you mentioned public folders.
You'll need to be a little more clear about what steps you've taken and describe the problem a little more clear.
You'll also need to have admin rights within Outlook, so if you have group policies pushing out, that could cause a conflict, but you would have needed to attached the group policy template for Office/Outlook into AD if that were the case. If you have no clue what I just said, then chances are you probably don't need to worry about it.
