Use the Get-PublicFolderStatistics cmdlet to retrieve statistical information about public folders, such as folder size and last logon time.

For information about the parameter sets in the Syntax section below, see Syntax.

Get-PublicFolderStatistics [-Identity <PublicFolderIdParameter>] [-DomainController <Fqdn>] [-Mailbox <MailboxIdParameter>] [-Organization <OrganizationIdParameter>] [-ResultSize <Unlimited>]

This example retrieves statistics about the public folder Marketing\2013\Pamphlets. The output of the Get-PublicFolderStatistics command is piped to the Format-List command so that all the available information is displayed in the result.
