+1 to davmail proxy; it is incredibly important to my productivity. I actually donated some money to the developer, but I should do it again.
The davmail code even handles Outlook having two-factor auth enabled, e.g. it'll recognize the extra form field, ask you to enter your token once, and then keep the session open, just like keeping the webapp loaded in your browser tab.
