Sync Outlook 2003 between two laptops (home network)

How can I sync Outlook 2003 between my two laptops (connected in a wireless home network)?

Is there any low-priced (or better yet, free) software that will automate the job?

I have tried MS WIndowsLiveSync and Good Sync, but neither one seems to work for me.

Any assistance will be most appreciated.

Thanks.
