title: How to view Azure AD schema
body: <p>How can I view the Azure Active Directory schema. 
  Does Microsoft provides any document for Azure AD schema(similar to <a href="https://msdn.microsoft.com/en-us/library/ms675085(v=vs.85).aspx" rel="nofollow noreferrer">this</a>)? </p>
  
  <p>I want to view all attributes of the User and Group in Azure AD with description. Similar document for Active Directory Domain Services is <a href="https://msdn.microsoft.com/en-us/library/ms675085(v=vs.85).aspx" rel="nofollow noreferrer">Active Directory Schema</a></p>
  
  <p>I am currently exploring the Azure AD Graph API and Microsoft Graph. I want to understand the difference between Active Directory Domain Services and Azure Active Directory with their attributes.</p>
  
  <p>Also, does Azure AD has <strong>USNChanged</strong> attribute?</p>
