Outlook intercepts and disables it because of course it does and instead pastes it with the formatting but with a little drop down box at the end of your text pass address you can click to remove the formatting like you tried to do with you with hotkeys.
I have to use Outlook for work, but never intentionally do so if I choice. Truly amazing. If there’s anything that can be messed up, it will be.
I use Firefox with DuckDuckGo. But I do agree that Google is so pervasive in the browser space that pasting text to the URL bar without further context can be reasonably understood in most instances, as sending data to Google.
