Dear Mo~561
Thanks for using Microsoft products and posting in the Community.
You describe that you were prompted to send a code to your email when you logged into your account, but you didn't receive it.
For this issue, you can set ******@accountprotection.microsoft.com as a safe sender in your mailbox.
If your bundled mailbox is Microsoft domain (outlook, hotmail, msn,live), you can log in your bundled mailbox on web-based outlook.live.com, click Settings-Mail-Spam on the top right, set account-security-noreply@ accountprotection.microsoft.com as the secure sender.
If your mailbox is a non-Microsoft domain mailbox, you can log in to your mailbox on the web side and set safe sender.
If you still can't receive the verification email, it may be that your current network environment has an abnormality in linking to the Microsoft verification server, you can wait for a while to receive the email, or you can ask your family or friends to log in your bundled mailbox on their devices to receive the verification email.
If your mailbox really can't receive the verification information, you can try to click “No such information” or other options when verifying, and check whether you enter the screen of modifying account binding information at last, if you can, you can modify the account binding information, add cell phone verification or other mailbox verification, but it takes 30 days to take effect! If you can, you can modify your account binding information, add cell phone verification or other email verification, but it takes 30 days to take effect.
