Hello,Tyler Kowalczik
Welcome to posting in the Microsoft Community.
I see that you mentioned that you are unable to reset the PIN and thus access your child's account and understand very well your frustration and confusion at this point. It is indeed frustrating that you have tried multiple methods in an attempt to try and resolve the issue and still no progress has been made. However, please be assured that we can resolve or bypass this issue with further attempts to allow the account to be used normally.
According to your description, there is a possibility that the system detects some abnormalities when sending the verification code to the mailbox, such as problems with the network environment, account synchronization status or device configuration. In this case, for security reasons, the system may refuse to send the verification code. In other words, even if the account itself has a normal mailbox, the problem may occur due to system policies or environmental factors.
For what it's worth, I note that you are currently able to log in to Windows. Given the difficulty in resolving the CAPTCHA issue immediately at this stage, you could try creating a new local account that you can use to temporarily resume normal computer use. Once you've done that, you can then bind that local account to your Microsoft account, which will allow you to use some basic online services. This is a temporary measure, but it can help you avoid the inconvenience of not being able to log in. Your data files will not be lost during the testing and migration of the account and can be found and copied to the new account directly from File Explorer under the C drive.
- Click on the Start button in the bottom left corner of the screen and select the Settings icon (gear shape).
- In the Settings menu, select the “Accounts” option.
- To add a user, click on “Family and other users” and then click on “Add another user” in the “Other users” section. For changing users, select the user account you want to change and click “Change Account Type”.
- Follow the prompts, enter the required information (e.g. email or username), set the new account type, and finally click “OK” to save the changes.
