I am working on an Outlook AddIn in Javascript. My functionality works well in Outlook Web but it isn't working in Outlook Desktop.
In Outlook Web i can see my console.log messages in the console of the browser. But i can't figure out how to do this with Outlook Desktop so i can properly debug my Desktop app.
Thank you for your help
For windows 10 and Outlook use Microsoft Edge DevTools Preview https://www.microsoft.com/en-us/p/microsoft-edge-devtools-preview/9mzbfrmz0mnj?activetab=pivot:overviewtab. I have just used it today with outlook addin
open your add-in on outlook.
go to and open one of: 32-Bit – C:\Windows\System32\F12\IEChooser.exe 64-Bit – C:\Windows\SysWOW64\F12\IEChooser.exe and there is your debugger.
As an alternate, you can use Fiddler or Procmon or debug addins using developer tools on Windows 10. Here's the documentation.
