How to install Chromium Edge extensions from enterprise server (outside Microsoft Store)?

@Robin L ,
I try to refer to the steps mentioned in the referenced thread and I am able to install the extension successfully.

Below are the answers to your questions.

1) If I have already hosted the .crx file on https://abc.com/resources/app.crx (Extension ID: abcabcabc), what would be the exact configuration/url to put in the extensionInstallForceList and extensioninstallsources respectively?

• For Configure extension and user script install sources policy, you need to set the domain address and then you can add * after it. For example: https://abc.com/*
• For Control which extensions are installed silently policy, you need to set the 2 parameters. [extensionID];[updateURL]
  • extensionID - the 32-letter string found on edge://extensions when in developer mode.
  • updateURL (optional) is the address of the Update Manifest XML document for the app or extension.

2) Is there any other configuration I might be missing?

You can try to check the following points that may help to fix the issue.

• check whether .crx file is hosted properly and you can download it if you add the URL in the address bar of the browser.
• Check the hosted .crx file is not corrupted.
• Make sure both policies are set properly as I described in the previous point.
• Make sure that you are passing the correct [extensionID].
• For testing purposes, try to only set the [extensionID] for Control which extensions are installed silently policy. If it works then you can try to add the [updateURL]. Note that these 2 parameters are separated by a semicolon.
• After applying the group policy, try to run the gpupdate command in the command prompt window to make sure that the latest changes are applied.

3) Once I have the setup completed, how long does it take for the extension to install on browser? so that I can verify whether my setup is working
The extension will get load immediately after you restart the browser.

I hope the above answers will help you to install the extension. If you have any further questions let us know about it. We will try to provide suggestions for it.
