Please note that this forum is not Microsoft support, this is a user-to-user support forum. Therefore, account verification methods, password recovery settings, mobile number associations, mailbox status, and tenant-specific email configurations cannot be validated through the Microsoft Q&A forum because forum users do not have access to customer environments or account data.
Regarding the password recovery issue, if the account is a Microsoft 365 account and you have administrator access, you can reset the user's MFA methods in Microsoft Entra admin center, please follow the steps in this article.
- Sign in to the Microsoft Entra admin center.
- Navigate to Users > All users.
- Select the affected user account.
- Open Authentication methods.
- Review the registered phone numbers and authentication methods.
- Remove any outdated or incorrect methods and ask the user to re-register MFA at their next sign-in. There is also an option to reset password, proceed if needed)
An administrator can also require the user to re-register multi-factor authentication methods by selecting Require re-register multi-factor authentication for the account. Then you will be able to set up the account from scratch.
Please try and let me know how it goes.
