Accessing old live.com (hotmail) accounts before it was migrated to new outlook.

Before migrating my old email address to outlook.com I had an old @live.com address (connected to hotmail) which I currently need to gain access to. I have some other accounts that used that email address and in order to use the password reset feature on those accounts I need to gain access to the email address to access the password reset links. Is there a way to still access my old account? The companies of the accounts I need to access can't verify the email, so they won't be able to change it over the phone.
