how to sync office 365 and iphone contacts

Phone users can be pretty unware, apparently even me. I have contacts from my iCloud account, my Gmail account, and my work Exchange account. Now that I'm faced with this issue, I realize that I'm not really sure how to tell where an individual contact comes from. It is setup on his phone as an Exchange account.

Recently my main email account moved over to Microsoft Exchange so I had to revamp my Outlook settings. Let me state that I only use GO Contacts for syncing contacts.

However, lately it has become a burden to use. I've been using GO Contact ever since I gave up iTunes for syncing between my Outlook contacts and iPhone contacts.
