Can not synchronize with PocketPC

I am using a laptop SONY, winxp pro with SP2 installed, a bluetooth
class1 (USB). I installed this bluetooth successfully, I can use file
transfer service, but I can not synchronize MS outlook with my PocketPC
via bluetooth connection. its returned the error: Failed in the
synchronize box.


I tried to enable "Auto discovery" function in bluetooth properties but
can not, it displayed the error below when I click apply:


"An error occurred..., the following setting were not saved

Discovery setting

Connection setting"


Please help me to fix this problem.
