Outlook 2007: ActiveSync 4.5: Win XP Pro. Following a reinstall of XP Pro, I find I am unable to sync my calendar, contacts and notes between my PC and my XDA Orbit. This has always been done automatically when I connect my XDA to my PC, thanks to ActiveSync. Not this time. I have tried reinstalling and updating both Outlook 2007 and ActiveSync. I have also tried copying the .pst file from my laptop. Sadly nothing works. Any ideas?
