Why I lost my microsoft account?

Possible reasons supported by Microsoft documentation:

1. The username is no longer recognized. If the sign-in page says Microsoft cannot find the account, use the Sign-in Helper tool first.
2. If the account has not been signed in to for more than two years, it may have been deleted automatically and cannot be reopened.
3. If the username or password stopped working, try the Recover your account flow and use any other alias or phone number that was added to the account.
4. If the account was closed, it can only be reopened during the 30-day or 60-day grace period. After that, it cannot be restored.

Recommended next steps:

1. Run the Sign-in Helper: Sign-in Helper
2. If the message says the username is not found, try account recovery here: Recover your account
3. Check that the email address is typed exactly right, including the correct domain, and try any other alias or phone number that may be on the account.
4. If the account was closed recently, try signing in at: Sign in If prompted for a security code and it succeeds, the account can be reopened.
5. If the username is still not found after recovery attempts, use Contact support from the Microsoft support page for username/password stopped working.

Microsoft also states that support agents cannot send password reset links or change account details for security reasons.
