created a new alias (the only one on the account).  I can use it to log in but when I tired to send email to it the next day from a different email client it was rejected by outlook.com saying it did not regcognize the account.  logged back into outlook.com (via the alias) and the alias does not show up in the options menu.  tried to add it again and it says that it is already an alias on the account.  it doesnt show up under the drop down for sending from in a new email either.  what is up?
