Well, if your device will sync with another computer running the same software then it seems that the issue is caused by the first pc and not your device. It sounds like you have some sort of conflict on that pc that does not let outlook install properly. I don't know what that would be.
I would backup the outlook files you want to sync to cds or dvds and then completely uninstall Office 2010 and Activesync. Then run a utility like Ccleaner(free) to remove any remnants including running the registry tool to remove any leftover keys or values. Then after a reboot reinstall Office 2010 and Activesync. Then delete the Activesync partnership on your TP2. Then after soft resetting TP2 hookup your TP2 to your PC and recreate the partnership and sync. Then unhook your TP2 from your computer. Then replace those Outlook backup files on your PC using the cd/dvds you made. Then reboot PC. Then after boot check and see if the files you installed are there on your PC. Then hook your TP2 up and resync. That should work.
