I get an error when opening: MMC has detected an error in a snap-in. It is
recommended that you shut down and restart MMC. then I click to report or
continue, if continue it opens up but you cant get into anything, in the
right bigger window it says MMC could not create snap-in. The snap-in might
have not been installed correctly. Name: Exchange System CLSID:
