told I could send and receive emails still with webtv.net, but I can send and not receive

I had to go to outlook.com when Microsoft closed WebTV.  We were told that we could still send and receive emails if we made a new alias.  I made an outlook address the primary.  The WebTV address can still send but it can't receive emails.  I checked the settings and they are set for sending and receiving emails.  People are getting back anything they send to my WebTV address as undeliverable.  Outlook even sent me an email stating that I could still send and receive mail to the old address.  I would appreciate some kind of solution.  Thanks.
