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).

		On desktop (Firefox) at least if I navigate to another folder, the URL changes but the browser back button doesn't change the view back to inbox. On mobile (iOS Safari), if I open an email, then try to navigate back, it takes me all the way back to the login page. The app also seems to use old-fashioned #anchor-based URLs rather than the navigation API. (Hilariously, I found a feedback link but it points to a 404.)
