I understand it’s very frustrating that the recovery form is being rejected even though you’ve copy-pasted the correct data. This usually means that, from the system’s perspective, the information still doesn’t clearly prove that you’re the rightful owner. You can submit the form again (up to two times per day), ideally from a trusted device and network where you’ve used the account before, without VPN. Unfortunately, if the recovery form continues to fail, Microsoft Support will give you the same guidance, as they don’t have access to change security details or bypass the automated process for your protection. In that case, the best course of action is to keep trying the form with as much accurate information as possible.
