Tbf, they did recently (I think) implement a feature where Edge would open with the email in a sidebar when opening links from outlook. So at least there’s some point to it.. if that’s a feature anyone actually wants..

I encountered this at work today. I just assumed I couldn't turn it off. Will def be looking for that setting tomorrow.

Outlook devs also doesn't know how the internet works. After all they use word as there email renderimg engine

I don't think I have ever seen that, but that could be because I only use Outlook on my work computer, which runs macOS. It looks like Edge works on macOS, but they don't seem to be pushing it.
