Get-MailboxStatistics command to run and not count hidden objects

Question

I have a script that generates a report on a set of mailboxes in an OU and how many messages are in the Inbox using the following command:
Get-MailboxFolderStatistics $mailbox -FolderScope Inbox | Where {$_.FolderPath -eq "/Inbox"}
There is a lot more to this script and it outputs a lot of information, but the count of items in the inbox is always wrong. It seems to be counting a lot of hidden items which users cannot see. From my reading in many forums this is a common problem, and
so far I have not found a solution.
Is there a way to fun the Get-MailboxFolderStatistics command and folder out hidden objects?

Answer 1

`Thank you for the response, but unfortunately I have been tasked to find a way to get this working. I understand that the Get-MailboxStatistics command is unable to filter out hidden items but I need to find a way to make this report possible. I can understand
the limitations of the command and the technology, but unfortunately the CEO of our company will not accept that as an answer and making this report working is not an option.
To at least allow the report to function for now, I have created a report which manually adjusts for the hidden objects in each box. This does require the manual effort however of adjusting an input file which keeps track of the number of hidden objects
in each box. Here is the code that generates the report:
$mailboxes = @(get-mailbox -OrganizationalUnit "<ORGANIZATION UNIT>")
$report = @()
foreach ($mailbox in $mailboxes)
    $inboxstats = Get-MailboxFolderStatistics $mailbox -FolderScope Inbox | Where {$_.FolderPath -eq "/Inbox"}
    $MailboxInfo = Get-MailboxStatistics $mailbox | Select LastLoggedOnUserAccount,LastLogonTime,LastLogoffTime
    $inboxstatCount = Get-MailboxFolderStatistics $mailbox -FolderScope Inbox | Where {$_.ItemsInFolder -gt 0 -and $_.FolderType -like "Inbox"}
    $RawInboxCount = $inboxstatCount.ItemsInFolder
    if ($mailbox.DisplayName -like "BillingFaxes")
        $CurrentHiddenCount = "$HiddenCountBillingFaxes"
    If ($mailbox.DisplayName -eq "callcenter")
        $CurrentHiddenCount = $HiddenCountcallcenter
    If ($mailbox.DisplayName -eq "lab")
        $CurrentHiddenCount = $HiddenCountcathlab
    If ($mailbox.DisplayName -eq "cviholter")
        $CurrentHiddenCount = $HiddenCountcviholter
    If ($mailbox.DisplayName -eq "medrecs")
        $CurrentHiddenCount = $HiddenCountmedrecs
    If ($mailbox.DisplayName -eq "appointments")
        $CurrentHiddenCount = $HiddenCountNFRappointments
    If ($mailbox.DisplayName -eq "pharmacy")
        $CurrentHiddenCount = $HiddenCountpharmacy
    If ($mailbox.DisplayName -eq "referrals")
        $CurrentHiddenCount = $HiddenCountreferrals
    If ($mailbox.DisplayName -eq "research")
        $CurrentHiddenCount = $HiddenCountresearch
    #else
    #{ $CurrentHiddenCount = "No Value" }
    #DIAGNOSTIC VALUES OUTPUT
    Write-Host "--------------------------------------------------------------"
    Write-Host "Current Mailbox" $mailbox.DisplayName
    Write-Host "Current Inbox Count from the report=" $RawInboxCount
    Write-Host "Current Hidden Count Number" $CurrentHiddenCount
    Write-Host "The Math should equal " ($RawInboxCount - $CurrentHiddenCount)
    $mbObj = New-Object PSObject
    $mbObj | Add-Member -MemberType NoteProperty -Name "Display Name" -Value $mailbox.DisplayName
    $mbObj | Add-Member -MemberType NoteProperty -Name "Inbox Size (Mb)" -Value $inboxstats.FolderSize.ToMB()
    $mbObj | Add-Member -MemberType NoteProperty -Name "Inbox Items" -Value ($RawInboxCount - $CurrentHiddenCount)
    $mbObj | Add-Member -MemberType NoteProperty -Name "Last User to Log On" -Value $MailboxInfo.LastLoggedOnUserAccount
    $mbObj | Add-Member -MemberType NoteProperty -Name "Time User was last logged in" -Value $MailboxInfo.LastLogonTime
    $mbObj | Add-Member -MemberType NoteProperty -Name "Time User last logged off" -Value $MailboxInfo.LastLogoffTime
    $report += $mbObj
All $Hidden----- variables are set to values from an imported file that must be updated regularly. It's messy, but at least it is getting the information we need to those that need it. If anyone can suggest a way to make this work without the constant need
to adjust the numbers for hidden items please let me know.
