+### Preventing administrator lockout
+
+To prevent an administrator from locking themselves out of their directory when creating a policy applied to **All users** and **All apps**, they will see the following warning.
+
+> Don't lock yourself out! We recommend applying a policy to a small set of users first to verify it behaves as expected. We also recommend excluding at least one administrator from this policy. This ensures that you still have access and can update a policy if a change is required. Please review the affected users and apps.
+
+By default the policy will provide an option to exclude the current user from the policy, but this default can be overridden by the administrator as shown in the following image.
