Adding a newly created outlook.com mail account to my Microsoft 365 subscription as main alias

KarinStark-2461 20

Please help!!!

I need to use my newly created outlook.com account as my primary alias on Microsoft 365 subscription but is saying this name is already taken ( which it has, by me a day ago) . I read on the forum I can’t add another Microsoft account into my existing one, but I really need the e-mail address I recently created. My question is: If I delete this newly created outlook.com account just created and wait 30 days or so, can I then use it selecting the first option then on the list “ create a new e-mail address and add it as a alias?”

Hello,

You cannot add an "existing" outlook.com or hotmail.com address to another Microsoft account.

Deleting it and waiting 30 days will not help, because once an outlook.com or hotmail.com address is deleted, it is gone for good. Microsoft doesn't recycle these user names so you will not be able to use it ever again.

Microsoft explains all of that here: https://support.microsoft.com/en-us/office/add-or-remove-an-email-alias-in-outlook-com-459b1989-356d-40fa-a689-8f285b13f1f2

What you can do -

Sign into https://account.live.com

Go to Your Info > Sign in preference, Add an alias.

Create new: this will allow you to use the native domain outlook.com to create a new alias. It will not be your already created outlook address, but if you want an outlook address, this is the only way.

Once added, make this new alias your primary alias.

@EmilyS726 Thank you so much for your reply. I did as you suggested and created a new Alias. (i did not yet made it is as primary as I am now a bit scared of things not working ) . So i sent a test e-mail to this newly created outlook.com alias from my AOL account , but i see the inbox name as something completely different , as outlook_BD4D2 etc etc... e-mail address. How can i remove this random e-mail address created with letters and numbers to keep only the newly created outlook i have?

Much appreciated for your help. Karin

Karin, you do need to make it primary alias in order for this email address to kick in.
