More to the point, it sounds as though his message store folder is not in the default location (i.e., he has moved it elsewhere) and since there is no registry info to support such a move, the program cannot find anything he moves.
Just an educated guess, but Windows Mail is not supported in Windows 7, so its use may well encounter problems, although I've been using Windows Mail in Windows 7 since the first beta without problems.
Good luck.
