A while back I mentioned our MAPI Stub Library. This is a couple of .cpp files you can drop in to your project instead of linking to mapi32.lib, Alternatively, you can build your own version of mapi32.lib. You can read more about the whys and wherefores on the codeplex site or in the MSDN article on MAPI linking.

We just updated the logic used to find the correct MAPI binary to both make it more correct and to simplify it. According to the dev who did the work, we were able to eliminate two thirds of the code from StubUtils.cpp. The code is now more future proof, so if you were using the original version, you should look at incorporating the update. MFCMAPI will use this new logic in its next build.

Enjoy!
