This app is rotten on Android. It's spam filter is awful. It doesn't notify you for "focussed" email, but will ping you every time a spam email arrives. It updates slower than logging in via a web browser. It's too slow in updating. An app wants to send you a security link for changing passwords or security settings? By the time this app finds that email, the link has time expired. How a software company such as Microsoft can have such a poorly implemented email app is beyond me. Avoid.
