I understand that would mean ms access and the like. However, I was
not aware that outlook pst files would be faced with multiple
accesses, I only have one instance of outlook running.

the point is to make afs a reliable place to put windows user home
directories, ie profiles. We could using some kind of profile
synchronization method -- or we could just map the whole profile into
afs. The later would be my preference.
