There is no manifest for MrMAPI, so when doing a build in VS 2012 (haven't checked 2010 yet), I get
res\MFCMapi.rc2(89): error RC2135: file not found: mrmapi.exe.manifest

Good catch - it'll be checked in for the next release. Meantime, you can copy/rename mfcmapi.exe.manifest and change MFCMAPI inside it to MrMAPI. That should get you building.
