Hello,
Thank you for using Microsoft products and posting to the community.
To turn off the Bing Chat box, click the menu in the top-right of the page, select Settings->More, and turn off "Chat response on result page".
If you have already tried turning off and still have it shown, please check whether you have Cookies and site data enabled for Bing, since the options are stored there.
You can also send feedback by clicking the feedback button in the bottom-right, or the "feedback" link at the bottom of the page.
You may submit feedback in the Microsoft Edge browser as well. Open the page in the Microsoft Edge browser, then use the shortcut keys "Alt" + "Shift" + "I" to open the feedback window or select the 3 dots in the top right, select Help and feedback, then choose Send feedback (Note that the feedback window will capture the current screen and URL link and email address, and you can add Attachment and record your problem), enter your problem, and click "Send".
Thanks for your patience and understanding.
Best Regards,
Johann - MSFT | Microsoft Community Support Specialist
