Windows 10: Unable to add alias to change account prime email

Situation - MS account is registered under email that is going away. I want to switch the default email to an existing Outlook.com email and I keep getting the message "This email address is already taken. Please try another." How do I get past this error? The current email address is also linked to my 360 subscription. The Outlook.com email address is deeply embedded in numerous accounts and deleting it is not a viable solution and I really don't want to set up another email address just to monitor Microsoft emails and billing notices. How do I get past this? Thanks!

Unable to change primary alias - Microsoft Account

Hi John,

As per the description, you are experiencing issue with you are unable to change the primary alias for your Microsoft account on the system.

I certainly understand your concern and appreciate all your efforts in trying to fix this issue.

I would like to provide you with the information that
an account alias is an email address or phone number that you use to sign in to your Microsoft account. You can have multiple aliases, and use any of them with Microsoft services such as Outlook.com, Skype, OneDrive,
Office, Xbox, Windows and more.

Your primary alias appears on devices such as your Xbox, Surface, and Windows Phone, and is the email OneDrive sends from when you share. You can choose a different alias to be the primary one at any time.

An alias is also the best way to change your email, but keep all your mail.
Add an alias, then make the new alias primary. Then you can
keep or remove the original alias.

I would suggest you to try the following steps and check if that helps.

• Sign in to the
  Microsoft account website.
• Under Account aliases, click/tap on the Make primary link to the right of an
  
  added email alias you want to be your primary alias.

Note: The email alias at the top of the list without a Make primary link is your current primary alias.

• Uncheck the Send me promotional offers from Microsoft box if you like, and click/tap on Yes to confirm.

You may also try the following steps given below and check if that helps.

• Navigate to Start>Settings>Account>Your Account.
• In the right pane, click on Sign in with a local account instead.
• Provide your current Microsoft Account Password.
• Follow the on-screen instructions.
• You can leave the Enter Password option empty, however, it is highly recommended to keep a password on your system to keep it safe.
  

For reference:

I would suggest you to refer to the article given below and check if that helps.

Microsoft account email alias problem

i changed the alias and removed the default one, so now i have only the new one in the list...the default one that was their is gone

i did not know that removing the default alias would mean i would lose my original email address, because now my original email adress isnt working.

and on top of that, my new alias or should i say new email address isint recieving emails... over 20 years of usuing the same email address and its gone because i thought a alias was just a display name.

 

Microsoft account email alias problem

My default alias used to be my default email address.
Now I changed the alias not knowing that I would not be able to revert back to my @HOTmail.com alias.... so now unless I send a email to the alias all mail becomes undelivered. How can I switch the alias back to my default email. When I try in account settings it says this email is reserved ...
