Created an alias on my outlook account.

Unable to send an email from this new alias email address.  When I click on 'New - write a new message' I only have my original email address listed to send from - no new alias email address.

Unable to receive an email addressed to new alias email address.  I have sent test emails from a number of sources and they do not arrive in my outlook inbox.

The messages are bounced with the sender receiving the following message:

"SNT0-MC1-F15.Snt0.hotmail.com rejected your message to the following e-mail addresses:

*** Email address is removed for privacy *** (*** Email address is removed for privacy ***)


SNT0-MC1-F15.Snt0.hotmail.com gave this error:
Requested action not taken: mailbox unavailable"

Please help.

Thanks.
