Phone not receiving email from Outlook.com Begining August 22 2013 – Alias email ?

I use a Google Nexus 4 with Net 10 ATT&T sim card. My outlook.com email is not reaching my phone as of August 22, 2013. I have using either the outlook android app or Mail Droid.

Interesting, I just received to my phone "welcome to the Microsoft community" to my main outlook.com account.

The issue seems to be with the Alias email accounts that worked just fine until August 22, 2013.

Odd I just received the "welcome to Microsoft community" to my alias outlook.com account, but have received no other mail to the Alias account during this time?

What is wrong?

I did a test email from my aol.com account to my main outlook.com address and I got a returned to sender message:

RFC822 header of the original email message.

 host mx1.Hotmail.com(65.55.92.136 said: 550 Requested action not taken mailbox unavailable

Then sent an aol.com message to my main outlook.com account and cc to the alias outlook.com and received the return to sender on the main outlook.com account, but received the email on the alias outlook.com accounts when signing in online. But these email were not delivered to my outlook.com email app on my phone.

What is going on here?

Thanks, I know sugar gets more results than vinegar!
