Ability to forward email with message headers
With the need to be more diligent about possible malicious emails, the new Outllook.com has made it harder to verify who an email is from and if the links will take you to where they appear to go. The ability to easily view the message headers has now been hidden and apparently you can't even view them if you use Mail or Outlook instead of the web interface. This is decremental to being able to identify a potentially malicious email.
Please allow message headers to be viewed by default on outlook.com and also in Mail and Outlook applications. There should also be an option to forward the message and message headers so that when a company asks for them it is easily doable by even those with a limited understanding of what that means.
