Like most microsoft applications nowadays, this is muddled and confused in its design. The inbox organises things for you and ends up hard to navigate. Some messages just dissapear, tidied away by the app, others get grouped together in ways that are unhelpful, their content hidden. Actual contacts in my address book don't appear as suggestions when I type, but misspelt mistakes do. What this app needs desperatly is a 'clean mode' where it just shows you your emails, unmolested.
