In outlook when I click on Tools Options Security and select my own
certificate there is a reigstry entry in the registry at the following path

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows
Messaging Subsystem\Profiles\Outlook\c02ebc5353d9cd11975200a a004ae40e

In here there is a value 11020355 which contains some binary data.

Now if I want to automate this process in an .exe and in my c++ code I want
to associate the certificate that I have created with outlook email client is
this possible? Are there any APIS or any way that I can do this?

Thank you.
