What kind of monkey in R&D thought this was a good idea, Or that people would want it? MS has been driving Skype and OutLook/Hotmail into the ground ever since they acquired it. Looks like GMail is now my main account.
Somewhat because of poor design direction as mentioned above, But mostly because 90% of automatic emailing bots for registration sites tend to ignore outlook emails because 90% of their spam gets shuffled over from outlook accounts.
Please stop trying to make the software 'pretty' or 'more productive'
(It is neither!) and perhaps spend all that time and effort on finally dealing with the spam and ident spoofing problems.
