Office Add-ins should run in Edge, not IE11
At the moment Word runs Add-ins in IE11
IE11 doesnt support ES2016, and is therefore much harder to develop for than all of the other newer browsers (Safari, Chrome, Edge).
Word should run Add-ins in Edge
We are actively working on this feature and will share more details on availability as soon as we can.

Additionally Save as web also should considering save for Edge HTML 5 above IE 6 and above

Will this only be in Win10? I assume those on Windows 7/8/8.1 will still be running IE.

It would also be nice to replace Excel Mac browser with something that support ES6.

Versions of webpack-dev-server after 2.7.1 don't support IE11, so switching from IE11 to Edge will help developers using common build tools like @angular/cli. Please prioritize this!

Thats great! If I could just add an extra suggestion for awesomeness: make sure that edge's "developer tools/js debugger" is available when running add-ins in Word
The same applies to the Excel I think.
