I tried to run MFCMAPI without MAPICDO installed, but I get the error when trying to call MAPIInitialize(NULL):
"There is no email program associated to perform the requested action. Please install an email program or,...".
HKLM\SOFTWARE\Clients\Mail (Default) points to "Microsoft Outlook Virtual". It looks like Outlook 2010 doesn't have extended MAPI support itself on my machine.
That's why I installed MAPICDO on the same machine.
I have a trial and not activated Outlook. Possibly I just need to install full version of MS Office?
