guys i found a solution to get it to work that doesnt involve resetting app preferences (which is annoying because it resets it for everything!!!!)
basically, have tiles notifications with numbers turned on > in emails, go to notifications, and put yes for the accounts > but if you dont like the push notifications set the importance to LOW!!! > in emails set sync schedule to auto (when received).
to recap, here's a checklist:
in apps, click emails, then notifications make sure app icon badges is on
for each email account, set yes to notifications, but change importance to LOW if you dont want push notifications to drop down screen, and make sure app icon badges is swiped blue to on.
in settings>notifications > notifications on home screen, make sure app icon badges is on, with either show with dot or number (your choice)
for each email account, make sure your sync schedule is AUTO (when received)
boom. the second you get a new email, the number will appear.
hope that helps, i like it because constantly resetting preferences would be irritating!
