i can work my way through setting up outlook.com with my own domain, no problem

but i currently have 3 outlook email address, 1 primary and 2 aliases (under the primary)

call them *** Email address is removed for privacy *** and *** Email address is removed for privacy *** and *** Email address is removed for privacy ***

i would like to end up with my own domain as my primary outlook.com address and then have my current *** Email address is removed for privacy *** as an alias and keep one of the other 2 current aliases (i would delete one)

so i would like to have

primary.com as my main address

*** Email address is removed for privacy *** as an alias

*** Email address is removed for privacy *** as a second alias

obviously all seen with a single sign on in a single account

if this makes sense, can anyone kindly tell me if this is doable 

i guess i could try but i just don't want to fiddle with all my mail records until i have a sense if it possible
