Using Classic Outlook on Windows for personal email, calendar, and contact management
That is exactly my situation. I started with the PWA version but had issues with Chrome not working properly and many reloads. Another problem I found is the ability to "Pin" the classic ribbon to the top of the page. I really like the classic ribbon but every time I open the app it defaults to the simplified ribbon. I thought once the desktop version came out there would be a way to set the default ribbon to the classic ribbon. But unfortunately there is no such option.
I've gone back to the PWA version until the desktop app has a save as function.
