Trying to re-enable disabled custom add-ins for outlook, but can't find in registry editor

I am building a custom add-in for outlook, but I couldn't use the add-in after adding to outlook, because it is inactive(disabled).

enter image description here

I created a custom add-in by following this documentation.

But after creating the add-in, I was not able to sideload using npm start.

So I used this. npm run dev-server.

And I added the add-in to outlook by following this guide - outlook on desktop.

At this moment, the custom add-in I just added is inactive, so I tried to troubleshoot this.

The documentation says I should go to File->Slow and Disabled COM Add-ins and enable the disabled add-in, but there were nothing in the option.

And also I tried to find add-ins in the system registry and set to enable always, but I couldn't find the added custom add-in either.

Did I miss anything or ...?

Even if the add-in is active, but it doesn't work.

I signed in with my work email and am using the latest version of Office365.

Thank you.

  • You are mixing web and COM add-ins for Outlook. It seems a web add-in was created using the yeoman generator and sideloaded into your Outlook account. Note, web add-ins work for Exchange profiles only (including O365). Most probably you are trying to run the add-in against a non-Exchange account in Outlook.

    But the troubleshooting steps described in the post are related to COM add-ins only (VSTO based ones too).
