Cannot send email - no account?

Ok after digging up what airsync is about, I found this

So many questions:

  1. Why am I supposed to bother about these details as a customer?
  2. If you guys know the problem, why don’t you make it the default protocol for Hotmail/outlook accounts in the first place?
  3. The logic behind saying “no account” still doesn’t make sense. A reasonable manager would have asked his programmer to give a message saying something like “existing accounts not configured correctly. Please refer to so and so section for help”

This design simply sucks. There is no semblance of usability here.

Update:
Now I found this:

Says MS stopped supporting airsync. So I’m confused. What exactly is the problem ?
