We're in the process of migrating from 2003 to 2010. I need to create a powershell command that can export to .csv the user names, mailbox size, database name and item count of all the users remaining on the 2003 Exchange server. What's the best way to do this?

You can use ESM 2003 and export the list. Go to ESM drill down to the database click on mailboxes and export to txt then import to CSV. If you can't see the columns you want then add the in. Sukh

You could consider using the Power Gui Tools which I find really useful. Download PowerGUI at http://powergui.org and install it on your machine Import the Exchange 2003 PowerGUI powerpack http://powergui.org/entry.jspa?categoryID=47&externalID=1956 To Install the Exchange 2003 PowerPack download it Launch the PowerGui Administrative Console (As an administrator) Click on File -> PowerPack Management Click on the Import... button and navigate to the Exchange Powerpack you downloaded You should now seee an Exchange 2003 node in the Navigation Tree Click on the Exchange 2003 node, Mailboxes and select the "Get-2k3Mailboxes" node A list of all mailboxes should appear and you can click on the Export to CSV button in the top right hand "Actions Pane" You can incorporate the code to do other stuff should you need to do anything fancy and you also have filter options.
