Update Your Email Address via Microsoft Account Settings

Use the official Microsoft account management portal to add a new alias and set it as your primary login name.

Microsoft accounts use 'aliases' for login names. To change your login email, you need to add a new alias to your account and make it the primary one. Your account data, subscriptions, and contacts will automatically carry over to the new login name.

Sign In to Your Account

Go to the Microsoft account website and sign in with your current email address and password.

Access Profile Information

Click on 'Your info' at the top of the navigation menu, then select 'Edit account info' under the Account info section.

Verify Your Identity

Complete any required security checks by entering a verification code sent to your registered phone number or backup email address.

Add a New Alias

Click on 'Add email' or 'Add phone number' to create a new alias for your Microsoft account.

Set as Primary Login

Once the new alias is added and verified, click 'Make primary' next to the new email address to start using it as your main login name.

Alias Rules and Restrictions: You cannot add an email address that is already associated with another Microsoft account as an alias.

Frequently Asked Questions

Will changing my primary alias delete my old email address?

No, changing your primary alias only updates your main login name. Your old email address will remain as a secondary alias on your account unless you manually choose to click 'Remove' next to it.

How long does it take for the new login name to sync?

It usually takes up to 48 hours for your new primary alias to update and sync across all Microsoft apps and services, including Xbox, Outlook, Windows, and Office.

Can I use a non-Microsoft email address as my login name?

Yes, you can add third-party email addresses (like Gmail or Yahoo) as an alias to your Microsoft account, provided they are not already linked to a different Microsoft account.

What happens to my subscriptions if I change my email address?

Your subscriptions, digital purchases, and cloud files are tied to your Microsoft account ID itself, not the specific alias. Changing your email address will not affect your existing subscriptions or data.
