owa is so much better than outlook for me, at least for my work email. There’s actual dark mode, the servers seem to do all the heavy lifting so it never seems slow, the attachment preview is better and i can download a message as .eml instead of proprietary .msg format. Probably once a day I have to hit F5 because it starts acting weird. You can also make it a PWA. Seriously if you have to use corporate email give OWA a shot.
