Get default MAPI client (Outlook, etc.)

We have a MAPI class and needs to do some refactoring. 1. Locate the default email client using the registry. That would be Microsoft Outlook in most case, so you MUST have Microsoft Outlook installed. 2. Avoid any Windows message boxes "No default MAPI client defined" - we want smooth operation. 3. Should work on Windows 7, 8, 8.1 and 10 with Outlook or any other MAPI client installed, win 32 / 64. 4. When the default MAPI client is found, the program should also open the MAPI DLL (using LoadDLL) and initialize it by calling MAPIInitialize. General requirements: Deliverables should be in Win32 API, C++, Visual Studio 2013. Can be a console application. No UI is required, just the result: "MAPI client is ..." Should not require any external DLLs.
