Remove Alias

Warning When removing an email alias that’s a Microsoft domain (such as @Outlook.com, @Live.com, or @Hotmail.com), that email is completely deleted from our systems and can no longer be used to send or receive emails. It won’t be available for use again as an alias on another account. Microsoft does not recycle email addresses, so it may not be reclaimed at a future time.

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

Add new alias

  2. Go to Your info at the top of the page.
  3. Select Manage how you sign in to Microsoft.
  4. You may be asked to verify your account before changes can be made. Follow the instructions 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. You’ll be returned to the previous screen. Select Verify and follow the instructions provided.
    • Or, select Add phone number. Enter the phone number 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 an alias on another account can’t be used.

It can take up to 48 hours for the change to be implemented across all Microsoft services. If you sign in to your Microsoft account on an Xbox One console by using your Kinect sensor, you might temporarily be asked to manually sign in with a controller. If you’re still being asked to manually sign in after 2 days, try removing your account from the console and then adding it back.You can use any email address or phone number you have listed as an alias to sign in. To make it harder for someone to break into your account, change your sign-in preferences to turn off any alias you don’t want used to sign in.
