how to gain access to my old hotmail email

I have an instagram account. Instagram reset my password for security purposes. Instagram asked for my email to reset my password, in whichI gave it to them. When I went to check for the password reset email, nothing came up. That's when I realized that Hotmail upgraded to outlook and in order to now recieve e-mails under this account I have to change it to *** Email address is removed for privacy ***. I Need to access my old hotmail (the one I had before the update)  because that's where the email is. Is there any possible way that you all can search and see if it was mistakenly deleted? I need that email and thanks to Hotmail update, I don't have immediate access to my old emails.
