Long time lurker here...finally needs some community input.

I'm hiding/showing a bunch of this elements in an email using a combination of media queries and conditionals.

Only one email client is causing us issues and thats Windows 8.1 Mail (Desktop). It doesnt seem to think it's MSO, IE (or even IEMOBILE [desperation])

So the usual, doesnt work:

<!--[if (gte mso 9)|(IE)|(IEMobile)]>
        <style type="text/css">
            .style {}

I thought perhaps that css styles weren't supported, but then

        <!--[if (gte mso 9)|(IE)|(IEMobile)]>

doesn't work either. Has anyone got a way of targetting the Mail app?

Thanks all
