I recently registered a new custom domain account and in my Windows Live Admin Center I created a few users accounts. I want to use the SDK tools available in order to create a custom domain alias for users. For example say  First@domain to be an alias for First.Last@domain as Info@domain to go to First.Last@domain However, as I had already created and subsequently deleted the First.Last@domain account, I receive an "Error 9003: Passport error."

 

NOTE:  I understand that creating a custom domain alias is not possible on the Admin Center.  I am basically requesting assistance with permanently deleting such "ghost" records that apparently persist on Microsoft's side even though they were deleted in the Admin Center -- presumably this is to allow them to be restored if "accidentally" deleted or other such activity.
