Answer 2

As far as I know Outlook 2007 is 32 bit.   Isn't only Outloook 2010 64 bit?

 

Answer 3

if your outlook is 32bit, then you don't 64bit MAPI.

Are you running the MAPI code in a service?

Answer 4

No this is code is a separate process outside of our main app but it does not run as a service. 

Answer 5

Thanks to Sheng's reply. I think that Sheng is saying:

64-Bit MAPI Application and 32-Bit Outlook
64-bit MAPI applications are not supported to run on a computer installed with 32-bit Outlook and 32-bit or 64-bit Windows. The application developer must update and rebuild the application as a 32-bit application to work with 32-bit Outlook. Use the updated MAPI header files, which you can download at Outlook 2010: MAPI Header Files. Developers can use this same set of MAPI header files to build both 32-bit and 64-bit MAPI applications.
