What Outlook data is not synchronized?
Data that isn’t supported by Google Apps or is otherwise incompatible. This includes Outlook tasks, notes, journal entries, follow-up flags, distribution lists, rich formatting in contacts, and more. You can continue to use these features in Outlook, and in some cases you can use equivalent features in Google Apps. But the data isn’t synchronized back and forth. For a complete list of features that aren’t synchronized, see this feature compatibility chart.
