How to increase Size of OST in Cached Exchange mode on Outlook 2003

On a 2003 Small business server we have group policies set for outlook to use unicode for OST's and maximum size as 8GB.   On a client their OST that is setup with Cached exchang mode enabled is not able to write any more data to the OST, its maxing out at 4GB.   I'm assuming the OST is in unicode format already as its beyone 2 GB.     But either way the OST was created before we applied the new policy.  

How can i get the OST restriction of 4 GB increased so we can continue to use the Current OST in outook.   Any help would be appriciated.   Also note that i did go in the registry on the pc and modify policies outlook pst size as well.

If you have having a file limitation error at 4GB, I would be wondering what file system the client computer is using.

FAT32 has a 4GB limit, and coincidences like that just can't be ignored.
