Good morning, when I open a file that contain DDE external links, I got a warning advice saying: "This workbook contains links to external data sources that use DDE (Dynamic Data Exchange) that may be unsafe and have been disabled. See File > Options > Trust Center for DDE configuration options" Clicking ok and the links seems working good. I'm finding a way to disable showing this warning. Windows 10 Excel version 1906 Any help appreciated. Thank you Marcel
