How to add a COM Add-in to Windows AppSource?

Copper Contributor

Hello, world!


Yes, I know that "Office VSTO add-ins and COM add-ins cannot be submitted to AppSource" but still is there any option to get listed with your VSTO+COM add-in for MS Outlook? Or we just need to rewrite the whole product from the base? Perhaps somebody had faced this situation?


Thanks for your help, guys!

I am facing the same need for an Excel VSTO complement.

MSIX packaging tool should , theorically, make it.

But when I tried the resulting package didn't work


Did you find a solution since your last post ?
