Yep, I've got XP SP2 Outlook 2003 syncing. I have an SL-5500, however. It may still work, though. Go get version 1.43E or 1.43G (same AFAIK) of Intellisync and follow the instructions in the other threads (symlink /home/root, create the linkver file, etc). Try setting Security to do Intellisync and if you can get it to respond, try setting it to Qtopie to get rid of the alerts.
