+         I'm using or want to use Azure Active Directory Application Proxy. Can I replace the `onmicrosoft.com` fallback domain of my tenant in Microsoft 365 as suggested in the article [Add and replace your onmicrosoft.com fallback domain in Microsoft 365](../../microsoft-365/admin/setup/add-or-replace-your-onmicrosoftcom-domain?view=o365-worldwide)? 
+        answer: |
+              No. You must use the original fallback domain.
