Suppose T and S are bounded adjointable operators between Hilbert C*-modules admitting bounded Moore-Penrose inverse operators. Some necessary and sufficient conditions are given for the reverse order law (T S) † = S † T † to hold. In particular, we show that the equality holds if and only if Ran(T
