Create a New Microsoft Email Address
To change your Microsoft email, you may choose to create a new account. With a new Microsoft account, you can export email messages, contacts, and other information from your old account and then import the data to use with your new email address.
Add an Alias to Your Microsoft Account
Microsoft also provides a quick and easy way to create an alias for your current account which is a good way to change your Microsoft email address. Alternatively, you can use another email address you have as an alias, if you prefer.
Log in with an Alias
By default, you can log in with any alias you add (you can have up to 10 at a time). You can change your sign-in preferences to select how you log in.
Change Your Primary Alias
You can choose the alias you want to appear as your primary email address.
Choose an Alias to Use on Outlook.com
If you use Outlook.com to read and send email messages, you can pick any of the aliases you create or add to appear in the From line of an email.
