Managing personal Outlook.com account settings, security, and privacy
No worries at all. I'm happy to provide any help. :)
Although, as much as I would like to give you any good news, I'm afraid what I have is rather not so good.
When an account becomes inactive for at least two years, they are automatically closed and cannot be reclaimed or recovered. Please see article below for reference.

In the event that the account remains open, the user will be prompted to fill in the Account Recovery form, which I believe you already went through. As this is fully automated, no one, not even Microsoft support is able to recover the account for you. If this fails continuously, the account is effectively gone.
Very sorry to have to give you this news.
