X1 support helped me solve this.
In Outlook 2013 -> File -> Account Settings -> Account Settings -> Highlight Exchange Account and click "Change..." right above it
In the window that opens there is an "Offline Settings" option.
There is a slider that is labled "Mail to keep offline:" and I adjusted the setting to "All."
Problem solved.
Thank you X1 Support.
