I need to remove an alias from a blocked microsoft account MSA

I have just been through a frustrating 3 months of Windows Phone support - 20 chats, numerous emails with the escalation team, etc.  My MSA, which i use on my Lumia 920 (WP8) was blocked from purchasing and no one could figure out why.  After 3 months, the escalation team came back to tell me that I am using an email address (at my own domain) which uses an "illegal" keyword in the email address.  Even though I have been using this since August 2012, on my WP7 phone, after switching to WP8 phone it became a problem of blocking my app purchases after about 30 days with WP8.

My problem:  I have already switched over to a new MSA and everything works great.  However, my preferred outllook email *** Email address is removed for privacy *** is an alias of the old account.  I need to have continued access to the alias and cannot just remove it and wait the 30 days or so for it to become available again. 

Question:  Can you help me to release the alias immediately so that I can add the alias to my new MSA?  I can provide you with all hte details and even the WPsupport case# for verification.  I don't want to just add the old account to my new account to access the email as I want to completely rid myself of the old MSA.

Thanks in advance!
