To be honest, outlook for mac isn’t particularly great either. It is not much of a step up from outlook web access, which is what I ended up using on linux after trying all the mail clients. Evolution with the ews plugin came close, but required a ton of configuration and the tasks integration was never quite right.

I've never used Outlook for Mac, but there's the Apple Mail.app on the mac which works great with Exchange. I'd choose it over Outlook on Windows every time.
