I will follow the search plan as outlined. The first step is to search for the specific command and the parameters. I'll also search for general context about msiexec and Sophos Outlook Add-in. search results for the specific command showed a Microsoft documentation page about msiexec, a blog post, and other links. The search for msiexec QR parameters showed Dell guides mentioning /qr.
