Change the email address or phone number for your Microsoft account

Notifications

Follow the steps on this page to change the Microsoft account email address or phone number (also known as your account alias or username) that you use to sign in.

Concerned about your licenses? Don’t worry—if you change your account alias, or remove an alias and then add a new one, all licenses linked to your Microsoft account will remain with your account.

Remove an existing alias from your Microsoft account

Warning When removing an email alias that’s connected to a Microsoft domain (such as @Outlook.com, @Live.com, or @Hotmail.com), that email is completely deleted from our systems and can’t be used to send or receive emails. It won’t be available for use again as an alias on another account. Microsoft doesn’t recycle email addresses, so it can’t be reclaimed at a future time.

Sign in to your account by using your existing alias and password.
Sign in to your account
Go to Your info at the top of the page.
Select Manage how you sign in to Microsoft.
Select the alias that you want to remove.
- If it’s a primary alias, select a new primary before you remove the old one. To do so, select one of the other aliases that are on the account, and then select Make primary.
- You’ll use this new primary alias to send and receive emails, access your Microsoft account information, and appear on devices.
To remove the email address or phone number that you no longer want, select the option Remove that’s next to it, and then follow the instructions that are provided.

Add a new alias to your Microsoft account

Sign in to your account by using your existing alias and password.
Sign in to your account
Go to Your info at the top of the page.
Select Manage how you sign in to Microsoft.
You might be asked to verify your account before any changes can be made. Follow the instructions that are provided to select your alias:
- Select Add email. You can create either a new Outlook.com email address or add an address that you already have. Then, select Add alias. After you’re returned to the previous screen, select Verify, and then follow the instructions that are provided.
- Or, select Add phone number. Enter the phone number that you want to use, and then select Next. When you add a new phone number, we'll send a text message to that number to verify it. Enter the code in the text message, and then select Next.

Note Email addresses and phone numbers that are already set up as an alias on another account can’t be used.

You can use any email address or phone number that you’ve listed as an alias to sign in. To make it more difficult for someone to break into your account, change your sign-in preferences to turn off any alias that you don't want used for accessing your account.

It can take up to 48 hours for the change to be implemented across all Microsoft services.
