1: Add a new alias.
- Sign in to your Microsoft account.
- Select Your Info.
- Select Manage your sign-in email or phone number.
- Because of the sensitive nature of changing your alias, you'll be prompted to enter the code that we send to the email or phone number you listed in your account as security information. This lets us know the request is coming from you.
- Select Add email alias.
- If you don't already have an email address, select Create a new email address and add it as an alias. Follow the instructions.
2.Set the new email address as the primary alias.
After you set the new email address as your primary alias, that email address will be displayed as your Microsoft account alias when you sign in to all devices and services. Here's how to make this change:
- Under Account alias, select aliases.
- Click or tap Make primary under the alias that you want as primary.
3: Remove the old email address you no longer want to use.
Select Remove next to the alias you want to remove. Follow the instructions provided.
Note It can take up to 48 hours for the change to your email address to be implemented on all Microsoft services.
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 in to your account, change your sign-in preferences to turn off any alias you don't want used to sign in.
