Use Microsoft’s forgotten-username lookup with any phone number or alternate email previously attached to the Xbox account; a gamertag alone cannot reveal the Microsoft account email.
1. Find the email address tied to the gamertag
- Open Forgotten your Microsoft account username ^1^.
- Enter a phone number or alternate email address that may have been added to the account.
- Request and enter the security code.
- Microsoft will display a masked username, such as
j*******@outlook.com, which should help identify the address.
Try every phone number and alternate email you may have used. One security contact can be associated with multiple Microsoft accounts.
2. If no security information was added
Because the broken HDMI port prevents checking the old Xbox display, check other places where the account may still be recorded:
- Windows 10/11 PC previously used with the account:
Start → Settings → Accounts → Email & app accounts - Word or Excel:
File → Account → Product Information → Belongs to - Search all email inboxes for Microsoft or Xbox purchase receipts, digital-game orders, subscriptions, or security messages.
- Check saved accounts and passwords in browsers or password managers on devices previously used for Xbox or Microsoft sign-in.
Microsoft documents these locations as alternatives when username lookup through security information is unavailable ^2^.
3. Sign in on the new Xbox
After identifying the email address:
- On the new Xbox, select Add new from the sign-in screen.
- Enter that exact Microsoft account email and its password.
- Complete any verification request.
Do not create a different Microsoft account expecting the gamertag, purchases, or game entitlements to transfer to it.
4. If the email is known but the password or verification method is unavailable
Use the Microsoft account recovery process ^3^:
- Provide a separate working email where Microsoft can contact you.
- Complete the form from a familiar device and location, if possible.
- Include as much account history as possible:
- Previous passwords
- Xbox account and purchase information
- Billing details
- Information about Microsoft services used
- The hardware ID of the old, frequently used Xbox, if you can obtain it without the display
- Microsoft normally sends the result to the contact email within 24 hours. If verification fails, the form can be retried up to twice per day.
If two-step verification was enabled and none of its verification methods remain accessible, the recovery form cannot bypass it. Microsoft Support also cannot disclose the account email, send a password-reset link, or manually change account details without successful validation.
