Exchange Mailbox Analysis

Question

I have a few users whose mailboxes seem to grow much more rapidly than others. For example we archived off a load of mail from one particular user less than a year ago to get his mailbox down to about 4GB (yes - I know, that's ridiculous, but we're running a project to implement auto-archiving / quotas etc).

Anyway, I want to know if there is a (preferably free) tool available that we can use to analyse the mailbox in terms of volumes/sizes of attachments. Something like TreeSize, but for Outlook OSTs (or even at source at the server).

(We're running Exchange 2003 SP2, Outlook 2010 clients)

Answer 1

As for free products: there are many tools for creating reports and gathering statistics at OutlookFreeware.com and I'm one if the developers. In particular, Attachment Report and Largest Folders can be very useful for you.

Answer 2

There's nothing native to Exchange server 2003 that will give you the information you need, but there's an entire industry built around Exchange management and reporting. This is just one of the tools available:
