1. alias was removed from ACCOUNT(A) 30 days ago. then was able to add the same alias to ACCOUNT(B), BUT unable to receive any message addressed to that alias in inbox under ACCOUNT(B).

2. went back to ACCOUNT(A) to check and found the same alias also listed here(!!!!!), under ACCOUNT(A):

inbox > options > your email accounts
https://col126.mail.live.com/mail/AccountList.aspx?n=296766471

but NOT listed here:

account settings > overview
https://account.live.com/summarypage.aspx?lc=1033&id=64855&mkt=en-us

and NOT here either:

account settings > overview > account aliases
https://account.live.com/names/Manage
======================================================

3. checked the inbox of ACCOUNT(A) again and found all CURRENT messages addressed to the alias appear there!!
