I am trying to install BES Express to use with my new insatll of Exchange 2010. I have encounted an "Unexpected MAPI error" when I reach this phase of the installation process. I have one back and verified all the preinstallation procedures and have ensured that I have the corrected MAPI files installed, and have exhausted most of the threads that I have found online documenting this problem.

Does anyone have a suggestion or insight on how to get over this problem?

You should post the relevant part of the installation log here, otherwise it is difficult to help. Also should you indicate which version of BES Express and on which OS you are installing. Also, is Exchange on the same box as BES?
