This usually means the Microsoft account security information on the PC still points to the wrong recovery email or phone, or the device is still tied to old account verification details.
Use this path to move verification back to the correct account owner:
- Sign in to the Microsoft account from a browser.
- Open the Advanced security options page.
- Select Add a new way to sign in or verify.
- Add the correct email address or phone number for security codes.
- Enter the code sent to that new method, then select Next.
- Expand the old security info that belongs to the wife’s email or phone and select Remove.
- Confirm the removal.
Important:
- Do not change all security info at the same time unless necessary. Microsoft warns that the account may be restricted for 30 days.
- If access still exists to some current security info, use that to add the new method first, then remove the old one.
If access has been lost to all current security info:
- Start sign-in to the Microsoft account.
- At Verify your identity, select I don't have any of these.
- Follow the prompts to replace the security info.
- After replacement, there is a 30-day wait before sign-in is available.
If the password is also unknown and there is no access to any security info:
- Review Help with the Microsoft account recovery form.
- Submit the account recovery form.
If suspicious or unauthorized sign-in prompts continue:
- Check the Recent activity page and mark activity that was not recognized.
- If the account may have been compromised, first run a full malware scan from Windows Security: Virus and threat protection > Scan options > Full scan > Scan now.
- After the scan, change or reset the password.
- Review account settings such as connected accounts, forwarding, and automatic replies.
If sign-in or verification still fails, use the Microsoft Sign-in helper. Support can also be contacted through Contact Microsoft Support, but support agents cannot send password reset links or change account details.
