Answer :
Microsoft might show conflicting password errors due to security features preventing password reuse. Thus, option (b) is correct.
- When you attempt to change your password, Microsoft checks the new password against your old one to ensure it isn't reused. This is to prevent password reuse, which is a common security risk.
- If you initially entered your old password incorrectly, it would display an error. After successfully changing to a new password, Microsoft's system logs it as a used password.
- Subsequently, when you try to reuse that previously logged password, the system recognizes it and alerts you that it's an old password being recycled.
In summary, the sequence of events you're experiencing is likely due to protective measures taken by Microsoft to ensure the security of your account, by preventing the reuse of passwords and maintaining password complexity.
