Trying to force the install of an extension in Microsoft Edge, the issue is that the extension is from the Chrome store and not the Microsoft Store. Allow extensions from other stores is already enabled. I am able to force any extension install from the MS store so I know that is working but i don't see how I tell it to go to the Chrome store.
I dont think you can force Chrome Extensions to install to Edge with a Configuration Profile. I would suggest running this question by technet, or bringing it up to Microsoft on your Tub (or open a case).
