how can I get rid of the leftover @gmail inbox once I disabled the forwarde account to Outlook.com

   I chose to add my gmail account to my Outlook.com program. I did all the forwarding in gmail and created the account so I could both send and recieve gmail from Outlook.com. I decided instead of getting both accouns in the one inboox to create @gmail inbox in the folder list of Outlook .com. When I disabled the gmail account or should I say disabled the forwarding to Outlook.com the @gmail folder inbox is still leftover in the Outlook.com folder list. How do I get rid of anything gmail that is leftover from the forwarding? Shouldn't that disappear once I reset everything back to the way it was in gmail and Outlook.com? I don't get emails but the folders are still there and I would really like them to disappear so the Outlook.com folder list is the way it was when I first started.
