Hi there! I get how frustrating this is. Unfortunately, Microsoft can’t reveal the email address behind a gamertag (like MineGamer6222) for privacy reasons — so the way back in is through the official Microsoft account username recovery and/or account recovery steps.
Here are some steps you can try to log back into your Microsoft account
- Try “Recover your username” (find the email/username hint)
Use Microsoft’s Recover your username page: Recover your username
Enter an email address or use the “Use phone number instead” option.
Microsoft will send a security code and then show a hint of the username (example format like j********@outlook.com).
This is usually the fastest way to rediscover the email.
- If you can’t get the username hint: use the Account Recovery Form
If you don’t recognize any recovery methods or can’t receive codes, Microsoft’s guidance is to use the account recovery form and provide as much detail as possible (old passwords, services used, etc.).
- Look for purchase/migration clues in old email receipts
Since you mentioned buying Minecraft Java Edition for Mac, search any email inboxes you might have used back then for:
“Mojang”, “Minecraft”, “Microsoft”, “Receipt”, “Order”, “Transaction”
These receipts often reveal which email address was used.
Also: Minecraft Java accounts were migrated to Microsoft accounts; after migration, signing in is tied to the Microsoft account. Minecraft’s help center notes the migration process ended (Dec 18, 2023) and support won’t assist with migration questions anymore — which makes recovering the Microsoft account email even more important.
I hope these steps can help you log back into your Microsoft account and log back into Minecraft soon, I personally also experienced this exact issue and these steps especially number 3 were able to help me regain access to my account.
