I had an issue logging into my work account on the actual outlook application recently so I tried the web version in the interim and it really is a lot better. I am not saying it is a world-beater but when they couldn't figure out my issue, I just let the ticket close.

I've been using OWA for a while as my primary work email and it's nice. I probably pin too much shit, but it's overall a good app. And since MS is web tech obsessed, OWA will replace Outlook at some point in the future. Project Monarch / One Outlook is still super half baked and predictably an awful RAM hog compared to the native app, but the writing is on the wall.

For this reason, I use OWA exclusively

Still waiting for them to replace the desktop app on macOS with an Electron app. The fact that no mobile/desktop client for Outlook doesn't have the like feature like Outlook Web is frustrating.
