In looking at setting from other mail apps on Android and the S4, there are many additional options that I don't have on Outlook.com app.  Specifically, I can set a ringtone as a message notification sound, which seems like it would be standard in any email application.  All you get is "Message Notification" and "Vibrate".  I would like to have a way to distinguish between various notifications I have (Exchange work email, Outlook.com, Lync, Twitter, Facebook, etc.)  Is there any way to do this with Outlook.com?
