Using Powershell with EWS - cannot see sender email address

I'm using Powershell with EWS to connect sort through a massive emailbox. It seems that the email properties show only the From header, not the actual sender header for an email. (The nice name, vs the actual email)

$emailProps = New-Object Microsoft.Exchange.WebServices.Data.PropertySet ([Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties)
$emailProps.RequestedBodyType = "Text"
.
.
.
$inboxItems = $service.FindItems($inboxFolder.Id,$searchFilter,$itemView)

$inboxItems | %{

$email = [Microsoft.Exchange.WebServices.Data.EmailMessage]::Bind($service, $_.Id, $emailProps)
