Managing personal Outlook.com account settings, security, and privacy
I understand that you can no longer receive verification codes because the old phone number has expired.
As the AI answer mentioned, if that number is your only verification method, look for“I don’t have any of these” when Microsoft asks you to verify your identity. This will allow you to start replacing the unavailable security information. Please note that Microsoft may apply a 30-day security waiting period, and Support cannot manually bypass or shorten it.
You can review the official guidance here: Microsoft account security info and verification codes
If you cannot find the replacement option or cannot begin the process, use the Microsoft account sign-in helper to identify the appropriate recovery steps. Thank you so much for your understanding.
