Hi kate,
Thank you for sharing your question. I understand how annoying it is to get locked out of your Hotmail, especially when you have 2FA on and can't use the recovery form. I am here to help.
This usually happens because Microsoft’s security blocks password resets if you mess up a bunch of times or log in weirdly. When 2FA is on, the account recovery form isn’t there, so you gotta use one of the ways to verify it that you set up for 2FA.
To fix it, try this,
Wait a day or two without trying anything else, since trying over and over can make the block last longer.
Use a private browser window and try logging in from a device or network you know is safe.
If you can still get into your account on any device, like a phone, use it to change or turn off your 2FA settings and add other ways to get it back.
If none of those verification things work, and you don’t have a recovery code, send in a Microsoft Account Reinstatement form at this link. It’s not the normal recovery form, and it's for accounts that got blocked. They’ll usually get back to you in a few days.
I hope this helps.
Best Regards,
Noel
