i have 5 mailbox databases assigned to 5 different hard disks. one particular hard disk is at 50GB free space out of 600GB. now i moved several mailboxes from this drive to another mailbox database located in another hard disk. i think i've moved about 20 mailboxes already but there is not much hard disk space gained.
should i move mailboxes out of this drive or i can't reclaim space no matter how many mailboxes i've moved out?
