I could not find the Limitations of Azure Virtual Desktop Based scenario's.

  5. Latest Updates with Client OS, and Remote Desktop Application is also Up to Date
  6. Windows Hello for Business Activated, Working Well as expected - PIN, Face Recognization...

Added Information:

  1. Remote Desktop Application helps to connect to the AVD Environment - with Regular Credential Based authentication.
  2. Remote Desktop Application failed to connect - With any other except credential based (Example : PIN, Fingerprint, Face Recognization...) - For any Applications which is Hosted in Azure VD (Example : Outlook, PowerPoint, Hosted Servers..)
  3. The Same error message appears if we take the RDP Session using MSTSCS Based Session
  4. All Azure VD Hosted Devices, Applications are accessible with out any issues using Browser. In General the browser based authentication will not ask for the Windows Hello For Busines based logins

Any Idea, if we have any Limitations with AVD + Windows Hello for Business.
