Windows 10: Grandparents Account Locked 2FA set to Landline

Good morning,My grandparents have locked the Microsoft account and are unable to receive the 2FA code. Apparently they got confused when setting 2FA and entered their landline which can't receive text messages. I'm not seeing any other option to send the code to their email for verification. Account recovery seems to be denied because 2FA was enabled. What next steps can we take?

2FA on account

Hi, I wanted to add 2FA on a microsoft account. I use the default mail app on 2 windows 10 pc's with outlook email addresses. I assumed when I activated 2FA that I would need to create an app password for each of the pc's. Do they need new app passwords or will they continue to work as before with 2FA enabled. Hope this makes sense thanks

 

Outlook with 2FA?

I use 2FA on outlook for my company email, and if it does not get a response from my mobile phone, it calls a phone mumber (that you supplied during 2FA setup) and you press # key to verify.

Obviously, use an alternative number different to mobile - landline even works.

 

Settings can't be opened using the built-in administrator account


Hello,
Unfortunately I have the same issue as Dabz from upgrading win7 to win10.
I've tried opening settings using all the suggested methods and it will not load using my account with Administrator access nor the built-in Administrator profile. I also tried other methods not listed such as using Run. Control panel is just a stepping stone to add users in Settings.
I'm also having explorer.exe issues, which I believe is preventing Settings from loading.
Using cmd (Admin) I successfully created a new user profile [and granted admin access also using cmd (Admin)], however win10 will not allow this account to log on. win10 does not list this new user within control panel but it does in the start menu. win10 will not allow to log in or switch to the new account via the start menu either.
I can access settings in Safe Mode but this will not allow me to create a new account.
Any help/suggestions will be greatly appreciated.
Cheers
