Using PowerShell to create a version of Get-MailboxStatistics for Exchange 2003.
Get-MailboxStatistics returns a set of information about a mailbox for Exchange 2007. It is possible to retrieve roughly the same information using WMI for Exchange 2003.
The differences
The following table notes the differences in property names between Exchange 2003 and Exchange 2007.
| Exchange 2007 | Exchange 2003 |
|---|---|
| AssociatedItemCount | AssocContentCount |
| DeletedItemCount | *Not available* |
| DisconnectDate | DateDiscoveredAbsentInDS |
| DisplayName | MailboxDisplayName |
| ItemCount | TotalItems |
| ObjectClass | Can be assumed to be Mailbox |
| StorageLimitStatus | StorageLimitInfo |
| TotalDeletedItemSize | DeletedMessageSizeExtended |
| TotalItemSize | Size |
| Database | Composed of Server, Storage Group and Store |
| DatabaseName | StoreName |
| Identity | MailboxGuid (repeat of above included for pipeline) |
| IsValid | *Not available* |
| OriginatingServer | Same as ServerName |
No formatting is applied to the output. The output from this function can be made to look like the Exchange 2007 version of Get-MailboxStatistics by using Format-Table.
Get-2003MailboxStatistics | Format-Table MailboxDisplayName, TotalItems, StorageLimitStatus, LastLogonTime
This is the code for the function, it is not as flexible as the Exchange 2007 version with regard to pipelines, but it should accept simple input and work in much the same way otherwise.
Usage examples
With a Mailbox Display Name Get-2003MailboxStatistics "Chris Dent" # With a Legacy Exchange DN ("-Identity" itself is optional) Get-2003MailboxStatistics -Identity "/O=SomeOrg/OU=AdminGroup/CN=RECIPIENTS/CN=Someone" # For a single Mailbox Database Get-2003MailboxStatistics -Database "Mailbox Database" # For a different server Get-2003MailboxStatistics -Server "ExchangeServer02"
