Outlook Add-in: fails to install with "Current User Only" option

The Outlook Plug-In is a feature of the Pexip Cloud Service which allows a subscriber with a Personal Video Account (PVA) and a paired Personal Virtual Meeting Room (VMR) to easily integrate with the Outlook Calendar and prepare meeting invitations.  Available for Microsoft Outlook on Microsoft Windows platforms, the Outlook Plug-in allows the subscriber to sign with his PVA credentials, which then allows the Plug-in to know which VMR they are associated with.  With a simple press of a button, the Outlook Plug-in will generate a meeting invitation which has all the details describing to an invitee how to join the VMR via various video technologies, and which can be placed on the user's Outlook Calendar.




Users attempting to install the Outlook Plug-In may find that the installation process fails during the user authentication step with one of the following error messages:


"Error: The underlying connection was closed: An unexpected error occurred on a receive."


"Error: The remote server returned an error: (404) Not Found."


It has been found that one of the error messages above is encountered when the installation type option for "Current User Only" is selected.  The installation type option "All Users" proceeds as expected, however, and after the installation is complete the user can successfully authenticate in with their username/password credentials for their PVA.




The steps described above should be sufficient to resolve the issue of the missing Outlook Plug-In button in the Outlook tools ribbon.  If the problem persists, contact Pexip Technical Support for assistance.
