Here are answers to some common questions about renaming your primary alias or adding an alias.
You can create up to ten new aliases per year, for an overall maximum of ten. Deleting an alias removes it from the overall count, but not the yearly limit.
Practically speaking, you can't turn an existing Microsoft account into an alias. You'd have to cancel the account, wait 365 days for the email address to be released (at which point it would be available to anyone) and then make the address an alias.
Yes. Here's how to set an alias to be your default email address:
Under Managing your account, click Your email accounts.
Under Default "From" address, select a default account.
You can also change what address an email is sent from while you're composing the email.
In your inbox, click New.
Click the down arrow next to the From address.
Choose the address from which to send the mail.
You can, but since aliases can be used to sign in, send and receive mail, and do pretty much anything else you can do with a primary alias, we don't recommend renaming. Instead you can Add an alias to your account.
If you still want to rename your primary alias:
In Outlook.com, click your user name in the upper-right corner.
Click Account settings. You might have to sign in again.
Click Overview, and then click Account aliases.
Check if the address you want to rename the primary alias to is already listed as an alias. If so, click Remove under the alias.
Click Remove alias.
Follow the instructions in Rename your primary alias.
If you remove an alias, the address will become available to anyone in 30 days.
If you rename an MSN account, you can't go back to the old address.
To go back to an old email address, you must be in the country in which you created the account.
Outlook.com turns your original email address into an alias. Aliases can be used to sign in, send mail from an app, and do pretty much anything else you can do with a primary alias.
No alias is created, so you can simply Rename your primary alias to your original address. You’ll want to do this before that address becomes available to anyone.
No, but you might be able to send and receive email from your custom domain account using Outlook.com. For details, see Send and receive mail from other email accounts.
