I blogged about how to find out mailbox use using MOM and the management pack the other week but if you don't have MOM in your environment this doesn't help you much. So I did some digging and found out that you can return information about the Exchange store using WMI and the Exchange_Mailbox class from the Exchange 2003 SDK.
here's an example of the VB script (copied from the SDK, not created by me!)
The following example shows how to retrieve a list of Exchange_Mailbox instances, and how to retrieve all the associated properties.
'===============================================================
' Purpose: Display each Exchange_Mailbox found for Exchange server, ' and show all properties
on the Exchange_Mailbox ' objects '
Change: cComputerName [string] the computer to access '
Output: Displays the name of each Exchange_Mailbox and properties
'===============================================================

Dim cComputerName
Const cWMINameSpace = "root/MicrosoftExchangeV2"
Const cWMIInstance = "Exchange_Mailbox"
cComputerName = "MyComputerNETBIOSName"
Dim strWinMgmts ' Connection string for WMI
Dim objWMIExchange ' Exchange Namespace WMI object
Dim listExchange_Mailboxs ' ExchangeLogons collection
Dim objExchange_Mailbox ' A single ExchangeLogon WMI object
' Create the object string, indicating WMI (winmgmts), using the
' current user credentials (impersonationLevel=impersonate),
' on the computer specified in the constant cComputerName, and
' using the CIM namespace for the Exchange provider.
strWinMgmts = "winmgmts:{impersonationLevel=impersonate}!//"& _ cComputerName&"/"&cWMINameSpace
Set objWMIExchange = GetObject(strWinMgmts)
' Verify we were able to correctly set the object.
If Err.Number <> 0 Then
WScript.Echo "ERROR: Unable to connect to the WMI namespace."

' Exchange_Mailbox instances in the Exchange namespace.
Set listExchange_Mailboxs = objWMIExchange.InstancesOf(cWMIInstance)
