Microsoft Alerts Azure Virtual Desktop Users to Black Screen Problem

Microsoft has warned that Azure Virtual Desktop (AVD) users may experience up to 30 minutes of black screens when logging in after applying the KB5040525 Windows 10 July 2024 preview update. Other symptoms include single sign-on (SSO) failures affecting Office applications like Outlook and Teams, which may block connections and prevent data synchronization, along with Office apps losing network connectivity while other applications, such as Edge, remain online.
