If your idea of quickly involves clicking on each user mailbox in turn and
then clicking on the general tab, then you are smoking something.
If you further wish to write a "script" to see the same information which requires you to supply data without any automatic enumeration....
Well, then I guess you should stick with Exchange :-)
