I can sync for about a week then I get the following error and the only
thing that I can do to allow me to sync again is a hard reset.

Windows CD Device -1 Sync Error
Error 'Target=Calendar" is reported by
"Windows CD Device" Unable to extract changes from datastore.

The first time I saw this issue, is was only for the calendar, but Inbox and
contacts would sync fine. Then the next time that I saw it, I had the same
error on Calendar, Inbox, and Contacts.
