The new OUTLOOK.com sucks in so many ways I don't have time to list them all.
The search perimeters are too narrow, it is useless.
Since you formed this partnership with UserVoice you have messed this site up so badly it has become a nightmare.
The "auto population" drop down list for contacts shows up prior to the fist letter being entered.
WAY TOO MANY THINGS TO LIST, YOU DON'T LISTEN
IT IS NOT FIT FOR BUSINESS!
