I've setup Outlook.com to sync with my android tablet through exchange.  Calendar syncs fine, mail syncs fine, but my contacts only sync about 1/10th of my contacts that I have.  There is no rhyme or reason as to which contacts it has chosen to sync, all that I know is that all of my available contacts are not syncing.  On my iPhone all contacts sync fine, as well as using Outlook connector.  What do I have to do in order to get all of my contacts to sync in all places?
