Connect to Outlook COM with Outlook 2016 Microsoft Store

Question

I'm using the standard COM API of Outlook. It works perfectly well. But since the release of Outlook 2016 in the Microsoft Store version, the COM is not accessible anymore.

Do you know any way to access it ?

Answer 1

I found the problem. Both things were happening, I was using a IUnknown instead of IDispatch, CoExInitialize was badly called, and my COM registration was messed up.
