Forgot my mail to my old account

The only supported way to recover a forgotten Microsoft account email is to use Microsoft’s self‑service tools and any clues from existing email accounts.

Follow these steps:

1. Check whether each email address is a Microsoft account
   • Go to the Microsoft account sign‑in page at https://account.microsoft.com and enter each email address that might be linked to the old Minecraft account.
   • If the message says “We couldn't find an account with that username” or “That Microsoft account doesn't exist”, that address is not a Microsoft account (or the account was closed). See: How to check if your email address is a Microsoft account.
   • If a password prompt appears, that email is a Microsoft account.
2. Use the Sign‑in Helper if the email/username is unclear
   • If the email or username is forgotten or only partially visible in other services, use the Sign‑in Helper tool to try to locate the correct Microsoft account:
     • Use the “Sign-in Helper tool” linked from the “I can’t sign in to my Microsoft account” article.
3. Look for Microsoft purchase/receipt emails
   • Check all email inboxes that might have been used over the years (including old or secondary addresses) for:
     • Purchase receipts for Minecraft Java or other Microsoft purchases.
     • Emails from Microsoft about account security, sign‑ins, or Xbox.
   • The article Check products or services where you used your Microsoft account recommends searching email accounts for Microsoft receipts; these often show which address is tied to the Microsoft account.
4. If the account email is found but the password is lost
   • Once the correct Microsoft account email is identified, reset the password:
     • Use Forgot password? on the Microsoft account sign‑in page and follow the steps in Reset your password.
5. If the account cannot be found or is reported as not existing
   • If the sign‑in page consistently reports that the account doesn’t exist, it may have been closed or deleted:
     • See How to check if your email address is a Microsoft account and I can't sign in to my Microsoft account for details.
   • If the account has been inactive for more than two years, it may have been permanently deleted and cannot be restored.

If none of the above steps reveal the old email address, there is no supported way to recover or reconstruct it purely from external services like NameMC; Microsoft support cannot bypass the official recovery and sign‑in tools.
