Powershell: Extract attachments from unread emails and save to a network share

Hello everyone

I currently have a vbs script (below) checking a mailbox, searching for unread emails and saving the attachment to a network share.
I'm looking at changing this to be run by a powershell script.

Can anyone help me convert it? I'm running exchange 2010.

Const olFolderInbox = 6

Set objOutlook = CreateObject("Outlook.Application")
Set objNamespace = objOutlook.GetNamespace("MAPI")
Set objMailbox = objNamespace.Folders("Mailbox - Docs")
Set objFolder = objMailbox.Folders("Inbox")

Set colItems = objFolder.Items
Set colFilteredItems = colItems.Restrict("[UnRead] = True")

For Each objMessage in colFilteredItems
    intCount = objMessage.Attachments.Count
    If intCount > 0 Then
        For i = 1 To intCount
            objMessage.Attachments.Item(i).SaveAsFile "\\server\share\" &  _
    End If
    objMessage.Unread = False

Since I do not have that much experience with vbscipts, I would suggest trying a converter, like this:

Normal conversion from vbs to powershell will not work, you should use EWS.

A simply transformation is (I've changed as little as possible, to allow for comparing):
$objOutlook   = New-Object -Com "Outlook.Application"
$objNamespace = $objOutlook.GetNamespace("MAPI")
$objMailbox   = $objNamespace.Folders.Item("Mailbox - Docs")
$objFolder    = $objMailbox.Folders.Item("Inbox")

$colItems         = $objFolder.Items
$colFilteredItems = $colItems.Restrict("[UnRead] = True")

ForEach ($objMessage in $colFilteredItems) {
    $intCount = $objMessage.Attachments.Count
    If ($intCount -gt 0) {
        For ($i=1; $i -le $intCount; $i++) {
            $objMessage.Attachments.Item($i).SaveAsFile("\\server\share\" +
    $objMessage.Unread = $false

The optimized script looks like this:
$objOutlook   = New-Object -Com "Outlook.Application"
$objMailbox   = $objOutlook.GetNamespace("MAPI").Folders.Item("Mailbox - Docs")

$objMailbox.Folders.Item("Inbox").Items.Restrict("[UnRead] = True") | 
  select -Expand Attachments | % {
    for ($i = $_.Count; $i; $i--) {
      $_.Parent.Unread = $false
