If you are trying to sync Apple MobileMe with Windows, be aware of some limitations. First, contact syncing will only work with Outlook 2003 and 2007, Outlook Express (Win XP), and Windows Contacts (Vista).

You also need the most up-to-date version of iTunes. See more troubleshooting help at Apple.
