I want to sync my Outlook 2007 info (contacts, calender, tasks and notes) to my iPhone 5. I'm currently using iTunes, which syncs my Outlook information to my iPhone, but it doesn't go both ways - if I add a contact or calender entry directly to my iPhone, it doesn't sync over to my Outlook. I see DejaOffice for iPhone. Would I also need to buy CompanionLink to put on my PC? Thanks.
