EMI shielding – does it need to be grounded?

Does a metal enclosure for controlling EMI emissions need to be grounded? I've had people tell me that an un-grounded enclosure will essentially turn into an antenna. I've also had other people tell me that there will be some attenuation although not as effective as if it were grounded.
