How do I Sync "Main" Phone numbers from iCloud to Outlook?

[tomdfw1]

I have lots of contacts on my iphone with phone numbers. But many times the phone numbers don't sync over to my Outlook sync from icloud even though the contact name/email does. I think this is because the phone number is called "Main" in iphone contacts/icloud and there is no "Main" phone number in Outlook. How can I get these over?
