Syncing Exchange Inbox subfolders to Blackberry

Question

Hello -

I have a Blackberry user that has organized his Outlook such that he manually sorts mail messages into specific subfolders.

Example -

      Inbox
          |---->Mail from 2004
                 |----> Personal
                 |----> Business
                           |---------> Travel
          |----> Mail from 2003

When using the Blackberry this user is able to view the folder, however the folder is empty, despite knowing the folder has mail messages in it on the Exchange server. The handheld appears to sync without issue. The user receives new mail messages. I have Folder Redirection enabled and all folders checked marked. I am using BES 4.0.

So, I guess my questions is this - How are the Outlook subfolders sync'd with the Hnadheld? Additionally, if a mail message is on the handheld is moved into a subfolder from the handheld, will it be sync'd on the Exchange server?

Thanks in advance!
