title: Create a Microsoft account programmatically
body: <p>I have an app that uses Azure Active Directory to authenticate and manage people. I need to be able sign-in anyone using their 3rd party accounts (Gmail, Yahoo, or any organizational account).</p>
  
  <p>Can I register people into my Azure AD if they have a 3rd party account, which is not a Microsoft account yet? I know I can send them to <a href="https://signup.live.com/" rel="nofollow">https://signup.live.com/</a> where their account will become a Microsoft account. The question is if I can do that programmatically when they register on my site? How?</p>
