At least for the Mac client, I think the native app, as slow as it is (possibly made worse due to corporate spyware), is better than OWA for several use cases: 1) searching mails is much faster locally 2) OWA zoom plugin requires re-auth every time SSO times out 3) most operations take 1-2 more clicks on OWA (marking meetings pub/priv, editing a meeting, etc). On the other hand I've not had plugins working on my native Outlook for several months...
