title: Azure Portal Error: Failed to start virtual machine 'xxxx'. Error: The Key Vault secret referenced with the URL 'xxxx' does not exist
body: <p>I have deleted some Key Vaults from my resource manager after assuming that they are not used anywhere in my configuration and that those were some leftovers from my testing. Now I can't start my virtual machines and this error message appears.</p>

  <p>Could you please advise me how to put my virtual machines back on track since I can't afford the time building them again?</p>
  
  <p>Thanks a lot.</p>
