Exchange Server: Exchange 2000Is there a way to create a report to show the monthly growth on a user's mailbox in Exchange System Manager? I want the ability to run a report of all mailboxes on a Store and track or show the monthly growth per mailbox.

You would need reporting software unless you scripted something yourself.Promodag offers such a thing: ( they are one of the most well-known)http://www.promodag.com/products/reports/features.aspxOther options:http://www.msexchange.org/software/Reporting/

also there are some good scripts available which will aslo serve your purpose see below http://gallery.technet.microsoft.com/ScriptCenter/en-us/441e4e39-30d0-405a-905d-81ed35702169Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Yes, Exchange doesn't have this feature, you need to leverage the third party solution.
