ActiveSync with Outlook 2013 only pulls the latest 25 emails

I have tried to set up Outlook 2013 and ActiveSync on 2 different computers and only the latest 25 emails are synced. I have deleted the account and recreated it later after more emails came into the inbox, and again only the latest 25 emails were pulled into Outlook.

Is there a setting somewhere that I am missing that is limiting this?
