 ## Configuring directory extension optional claims
 
-In addition to the standard optional claims set, you can also configure tokens to include extensions. For more info, see [the Microsoft Graph extensionProperty documentation](https://docs.microsoft.com/en-us/graph/api/resources/extensionproperty?view=graph-rest-1.0) - note that schema and open extensions are not supported by optional claims, only the AAD-Graph style directory extensions. This feature is useful for attaching additional user information that your app can use – for example, an additional identifier or important configuration option that the user has set. See the bottom of this page for an example.

 > [!NOTE]
 > - Directory schema extensions are an Azure AD-only feature, so if your application manifest requests a custom extension and an MSA user logs into your app, these extensions will not be returned.
