Send mail as: **User Name**
I found a problem with using this app with my google account. couples months ago I've changed my google account name. then changed again after few weeks later. When I sending emails from outlook it's still shows the previous name. I've tried to fixed this issue with google settings but there's no luck. And then I changed my phone couple months later and reinstalled outlook app. And yet it's still shows the previous name for google account. So I think "send mail as" feature is a perfect way to solve these kind of issues. I'm just suggesting that it's give an option to user to change display name, when sending emails.
