Add me to the list of folks who can't sync their iPhone to Outlook. After installing iTunes 7.3, whenever I launch Outlook (ver 2007), I get the application crash window (with the option to send an error report) followed by another message box that reads "Outlook experienced a serious problem with the 'outlook iTunes sync addin' add-in...", then it asks me if I want to disable the addin. The only way Outlook will run is if I disable the addin. But then I can't sync! I re-enabled the addin, but Outlook simply crashes again. Anyone else have this problem and found a workaround?
