Hopefully you worked this out. What the always cryptic Evernote "communication" people didn't explain clearly is that once you add it on the web in your 365 account it does indeed appear on your desktop. It actually is better than the old clipper widget in that it provides a dropdown for notebook and a place to search tags (why EN doesn't just give us a freaking tag dropdown I'll never know), and a place to add text. I was angry too until I rebooted outlook and the functionality appeared.
