Applies to all Barracuda Spam Firewall models 300 and higher using the Outlook Plugin, all firmware versions. Applies to Outlook Plugin versions 220.127.116.11 and above.
When installing the Outlook Plugin version 18.104.22.168 or above, when clicking the first Next button to begin the installation, if the installer crashes (sometimes with the error "This installation ended prematurely with an error"), you might try to install the plugin in a different way. You can run the .msi installer from the command line with the switch /quiet. This will perform a silent installation of the plugin, which may work better than the regular installation, especially on function-specific computers (Windows Advanced Server, Windows Terminal Server, etc) and Windows Vista machines.
For more information, please see the attached Outlook Plugin installation guide below.
