The Outlook web app breaks browser navigation, I thought we had that figured out in SPAs like, more than a decade ago. But it does load almost-instantly (less than a second) so that's nice at least.
Where does it break nav? Honest question, because I have been living inside it for almost 7 years now and actually prefer it to any of the desktop clients (except on the Mac).
