Outlook Deleting Fowarded Emails

Hello,

I turned off forwarding from my Outlook email to my gmail by following the online page: settings -> Mail -> forwarding but my email is still getting forwarded and getting deleted from my Outlook. How can I go about fixing this problem? I have attempted to follow many different tutorials that address the same type of issue, but none of them have proven effective. Additonally, when I look in the deleted folder of my Outlook email, the emails do not appear there as deleted and seemingly have disappeared from the server in general.

Thank you for your help!
