We are observing multiple incidents where users are unable to connect to Always On VPN (AOVPN) and are encountering issues with Microsoft Teams and Microsoft Outlook following the installation of the September Windows updates.

Reported issues include:

  • AOVPN failing to establish a connection.
  • Microsoft Teams/Microsoft Outlook not launching.
