outlook.com email addresses associated with alternative (other) account – recover?

Hi,
I have created a temporary e-mail address and forgot what it was. I later had some critical information sent to that e-mail address (purchase license code).
Is there a way to recover the e-mail address associated to the account that I have indicated as alternative (other) during sign up process? I know the alternative account, security questions and password, but not the email address to which I probably made a spello and didnt notice.

Thanks!
