I have list of users in Ad/Exchange online that we can view from https://portal.office.com/Admin/Default.aspx#ActiveUsersPage . I want to get some details (office phone, fax) for a specific user from SharePoint site. Is it possible? In other words, i am running javascript from mysite.sharepoint.com/sitepages/test.aspx and want to show an user detail that we have in https://portal.office.com/Admin/Default.aspx#ActiveUsersPage
Thanks in advance
