New Mail App doesn't recognize contacts

Setup the new mail app in Build 10547. All my contacts from outlook and google appear in the People app.
However, when I start a new email with my outlook , Google or Centurylink accounts the mail app doesn't show me my contacts email address.
I have to manually enter the email address. Is there any way to get the mail app to recognize my contacts in the people app.

Thanks

Well, I fixed my issue. Went to settings and privacy. Then turned on everything in the calendar, contacts, and email subsections. Now when I type the first 2 or 3 letters of the persons name in the TO section that person's email address shows up.
