Real tech people don't use IE.
Only businesses that locked themselves into some MS Office everything systems even bother paying for the webapp trash Microsoft sells. Outlook hasn't been particularly good for a decade now, but if you don't veer out of the bubble, how would anyone know? I'm aware that sounds like a dick answer, and regardless how you feel about me (and being blunt about it), it is every bit truth. Use a real browser, use a user agent switcher to spoof whatever IE browser, try it. I have yet to have issues getting sites that require IE to run on another browser with very little effort.
Real tech people just download iTunes to their leased Audi and sit on an umbrella shaft.
