I tried using the Mail app for my work Office 365 email account because the web UI is so awful. Turned out the app is pretty much exactly the same. Bulk operations, except deleting (the one bulk operation I never wanted), are pretty much impossible to do; simple UI features, like copy/paste are broken in several ways; search is close to useless; annoying extra "features" I have to turn off ("@" replies, chat). Any benefit OS integration provides is completely negated, and then some, by all the other inconveniences of the app.
