title: Implications of "Guest" on Azure AD account (not B2B)
body: <p>Let me start with my question's background, then ask the question:</p>
  <p>Scenario:</p>
  <ul>
  <li>Users are standard users in Azure AD - not B2B or B2C, just normal users</li>
  <li>The account is set to be a &quot;Guest&quot; account through <code>Set-AzureADUser -UserType Guest</code></li>
  </ul>
  <p>Justification:</p>
  <ul>
  <li>Setting a user as a <code>Guest</code> enables setting the options on a tenant to restrict access to information about other users, for example:</li>
  </ul>

  <ul>
  <li>As a software developer, you have a tenant for your customers, but you can't use B2B or B2C because some Azure services don't support them or you need capabilities such as On-Behalf-Of that those offerings don't have today</li>
  </ul>
  <p>Question:</p>
  <p>What are the other implications of setting the <code>UserType</code> flag to <code>Guest</code> besides offering the information restriction options and invite options shown earlier?</p>
  <p>I believe that my answer is at <a href="https://docs.microsoft.com/en-us/azure/active-directory/external-identities/user-properties" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/active-directory/external-identities/user-properties</a> where it reads in a note:</p>
  <blockquote>
  <p>The UserType has no relation to how the user signs in, the directory
  role of the user, and so on. This property simply indicates the user's
  relationship to the host organization and allows the organization to
  enforce policies that depend on this property.</p>
  </blockquote>
  <p>which means that ultimately there's no other impacts, but I would like some validation that I'm understanding that note correctly.</p>
