My contacts.pst has disappeared! I prefer to back up locally. After syncing my Outlook Contacts to iCloud, the contacts.pst (normally in AppData/Local/Microsoft/Outlook) has disappeared. It must be somewhere on my hard drive, undoubtedly under a new name, but where? I want to back-up (so I can retrieve it) locally. Help! Any ideas? (Windows7; Outlook 2007; iTunes latest version; iPhone iOS 7.0.4)
