Make the current email the primary alias of the existing Microsoft account, then remove or disable the previous alias; update payment and billing details separately because those records are not controlled solely by the sign-in alias.
1. Change the account’s primary email
Microsoft calls each email address attached to the same account an alias. Aliases share the account’s password, subscriptions, storage, contacts, and settings.^1^
- Open Manage how you sign in to Microsoft:
https://account.live.com/names/manage
- Sign in with your current email address.
- Under Account aliases:
- If the current email is listed, select Make primary beside it.
- If it is not listed, select Add email, add and verify it, and then select Make primary. An existing Gmail, Yahoo, or other non-Microsoft address can be added as an alias.^2^
- After confirming that the current address says primary alias, sign out and sign back in with that address.
- If the discontinued address is still listed, select Remove beside it.
Important: Removing an address ending in @outlook.com, @hotmail.com, @live.com, or @msn.com permanently deletes that address; it cannot later be reclaimed. If it is such an address and permanent deletion is not desired, leave it attached and use the current address as primary instead.^3^
Changing the primary alias does not rewrite every purchase or payment record.
- Payment method: Open Payment options, choose the relevant payment method, select View or edit card, update its information, and save.^4^
- Billing or shipping address: In the Microsoft account, open Billing & shipping addresses, edit the applicable entry, and save. Microsoft notes that changes apply to new purchases; previous purchases and an existing active subscription can continue displaying the former billing address.^5^
- Subscription payment details: Open Services & subscriptions, select Manage for Microsoft 365, and use Change payment or Change how you pay when available. If the subscription was purchased through Apple, Google, Amazon, or another retailer, its billing details must be managed through that provider.[^6^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Where can I manage my Microsoft 365 subscription? | Microsoft Support")
Historical orders may continue showing the information recorded when the purchase was made. Changing the alias or current billing details does not retroactively alter those completed records.
If the old address still appears
If it remains on the current account or subscription page after the current address is primary, use Microsoft’s guided support or Contact Support from the alias-management support page. Support can investigate display or billing-record issues, but agents cannot directly access and change account details on your behalf.^1^
