my email blocked cant receive cant send

Hello Nil Pat, 

Thank you for reaching out to the Microsoft Q&A. It sounds like the system is having trouble delivering the security code to your current mobile device.  

To regain access, please try the following steps: 

Step 1: Request the code again using another phone number. If your current mobile device is not receiving the code, you can try requesting it again using a different, non-VOIP phone number. Using a friend's or family member's standard mobile phone often resolves the issue when the system fails to send a code to your primary device.  

For more detailed information on how to do this, please refer to this article: Microsoft account has been locked. 

Step 2: Submit the Account Reinstatement form. If you try a different phone number and the system still fails to send the code or unlock the account, your next step is to submit the Microsoft Account Reinstatement form. This form escalates your case to the Microsoft safety team, who will manually review the block and help restore your access.  

Should you continue to experience login issues, please feel free to reply with a screenshot of the specific error prompt. This will allow me to investigate further and provide more targeted advice.Best regards,
