Show the recipient's email addresses not just the name.
Outlook often picks up the wrong email address for my contacts and uses those when I type the person's name as a mail recipient. For example Wunderlist notifications. Too many times I've sent the email to the wrong address. Please give me a chance to notice the address is wrong before sending.
Many phishing or fake emails come in with a forged display name, eg "John Smith <firstname.lastname@example.org>" and Outlook will only show the display name "John Smith"
This is very confusing for users, especially when fake messages come in with display names of people they correspond with regularly.
Please make Outlook always display the email address of a sender (which can't be faked) and not only the display name (which can be faked)

It should also be easier to remove "wrong" emails from the suggested emails list. I have wrong spellings of people's emails that show up over and over many times per day and I can't figure out where they are coming from.
This is an exisiting issue with new outlook app for android. The experience is not the same as iOS app

This is a serious phishing vulnerability. People are easily tricked into thinking they are replying to some one else. Leaking sensitive information etc. I would encourage our CIO to disallow outlook use until this is fixed.
