If you are not receiving the confirmation code for accessing your Outlook email, it is recommended to check your Junk Email or Spam folder to ensure that the email containing the verification code has not been misdirected there. Additionally, ensure that your phone number is correctly associated with your account and that there are no issues with your mobile service provider that could be preventing the receipt of SMS messages.
If the problem persists, consider reaching out to Microsoft support for further assistance with your account access issue.
