Windows Phone 7
Windows Phone does not support USB sync with Microsoft Outlook's Calendar, Contacts, Tasks, and Notes as opposed to older versions of Windows Mobile with Desktop ActiveSync. Syncing Contacts and Appointments is done via cloud-based services (Windows Live, Google, or Exchange Server), and no method to sync this information directly with a PC is provided. Third-party software, such as Akruto Sync, provides some of this functionality. A petition to Microsoft was filed to reinstate USB sync for Outlook.
