As some guidelines on net, this is the way I used to get live/hotmail contacts information:
call this url to get Access token: https://login.live.com/oauth20_authorize.srf?client_id=MyClientID&response_type=token&scope=MyScope&redirect_uri=https://login.live.com/oauth20_desktop.srf
Then call this to get all contacts: https://apis.live.net/v5.0/me/contacts?parameters-like-access-token-here
MyScope: wl.basic%20wl.contacts_emails%20wl.contacts_phone_numbers
This returns me all contacts name, emails, phones but lack of home fax and work fax, seems like wl.contacts_phone_numbers doesn't include fax numbers !
Can anyone help me what is the scope for getting full emails, phone and fax numbers ?
