To recover a locked account due to too many sign-in attempts, especially when you do not have access to the authenticator app, you can follow these steps:
- Wait for the Lockout Period: Typically, accounts are locked for a specific duration after multiple failed sign-in attempts. This period can vary, but it often lasts about 30 minutes. After this time, you can try signing in again.
- Use Security Information: If your global admin has enabled it, you can reset your password using your security information. This usually involves answering security questions or receiving a code via email or SMS.
- Contact Support: If you are still unable to access your account after the lockout period, you should contact Microsoft support for further assistance. You can find the appropriate contact at Support for Business Products.
- Account Recovery Options: If you are a part of a company or organization, reach out to your global admin for help. If you are an individual user, you may need to fill out an account recovery form, although you mentioned that it was rejected due to no purchases made on the account.
- Two-Factor Authentication Issues: If you lost access to your two-factor authentication device, you can visit the Contact us support page and select the product you need help with.
If these steps do not resolve your issue, consider providing as much information as possible to support to verify your identity and ownership of the account.
