MS Article: Emulate mobile devices (Device Emulation)

You might be able to pass it --use-mobile-user-agent, not sure what properties the control allows.

Out of curiosity why do you need the mobile version of a site?

I take it if you resize the control it doesn't use the media queries of a page to determine what to show and just adds scroll bars?

Can the Edge browser display mobile-friendly pages? Yes, absolutely! It can. Is this something that I've done with Microsoft Access? Nope. So yeah, if you want the database to display it in a mobile format, then there might be a way of forcefully telling the browser what user agent to send. I'm not exactly sure how to do that, but if I get some time, I'll look into it.
