So now with Graph API you can get the personal contacts and for developers, it will help you to tap into the rich functionality of mail or calendar means opening up richer scenarios with the user's contacts data. In addition, i would suggest you to go through the related documentation which talks about Why integrate with Outlook personal contacts.

Happy Programming!!
