On your phone you can not but if you login on your pc to outlook.com (with your ms account you use on your phone) and go to people there you can select then "all" and delete them.

On my 930 you simply go into your people app and select the three dot icon on the bottom right hand corner, under the menu that appears there is an entry "select contacts", go in there and then boxes appear to the left of your contacts. Choose the ones you want and then touch the trash can at the bottom of the phone.
