I'm trying to present management with a report of some sort that shows how much space each user is occupying in their Online Archive (exchange 2010). I've found countless reports which accomplish the above in regard to the Mailbox size (.csv or .htm dumps etc.), but I need one for the Online Archive specifically. Also, I'd really like to be able to do this with one script\command, instead of having to run a command against each mailbox individually. Thanks!
