Once you have configured the one-time setup of News Central, chances are you won’t need to revisit the setup. If you need to modify the setup to change the SharePoint Redirect Site URL or establish another OAuth client connection, the News Central Setup is available behind a URL.

1. On the SharePoint Online site, go to the browser address bar.
2. Append the URL with ?sb365-setup=true.
   For example, if your URL is https://mycompany.sharepoint.com/sites/sitename, append the URL with ?sb365-setup=true. Your URL will look like this:  https://mycompany.sharepoint.com/sites/sitename?sb365-setup=true
3. Press Enter on your keyboard.
   The News Central Setup dialog opens.
4. Modify your News Central settings.
