How can I view mailbox information in Exchange 2007 from PowerShell?

A. Mailboxes can be viewed via the Exchange 2007 Exchange Management Console, Recipient Configuration, Mailbox area. However, this doesn't give all information available. Using the Get-MailboxStatistics cmdlet, you can get detailed information about a mailbox size and limits. For example,

Get-MailboxStatistics jsavill | format-list
AssociatedItemCount : 102
DeletedItemCount : 11
DisconnectDate :
DisplayName : John Savill
ItemCount : 13439

To get more detailed information on a per-folder basis, use Get-MailboxFolderStatistics instead of Get-MailboxStatistics.
