How much do you think you will regain? If it isn't over 30%, I wouldn't bother. Has online maintenance run to completion since did the "clean out old users"? (Hunt for event log id 1121) Has your deleted mailbox retention timeframe been exceeded or did you manually purge the mailboxes? Regards, Michael B.
