Create RSS feed for Narrow casting

Question

We are using narrow casting and we can stream content to it using an RSS-feed.
We want to do the following: - Create an rss feed of an exchange (mailbox or calendar) using a script. I think it is just like this link. Or as shown below: 
###Code from http://poshcode.org/?show=669
# Creates an RSS feed
# Parameter input is for "site": Path, Title, Url, Description
# Pipeline input is for feed items: hashtable with Title, Link, Author, Description, and pubDate keys
Function New-RssFeed
param (
$Path = "$( throw 'Path is a mandatory parameter.' )",
$Title = "Site Title",
$Url = "http://$( $env:computername )",
$Description = "Description of site"
Begin {
# feed metadata
$encoding = [System.Text.Encoding]::UTF8
$writer = New-Object System.Xml.XmlTextWriter( $Path, $encoding )
$writer.WriteStartDocument()
$writer.WriteStartElement( "rss" )
$writer.WriteAttributeString( "version", "2.0" )
$writer.WriteStartElement( "channel" )
$writer.WriteElementString( "title", $Title )
$writer.WriteElementString( "link", $Url )
$writer.WriteElementString( "description", $Description )
Process {
# Construct feed items
$writer.WriteStartElement( "item" )
$writer.WriteElementString( "title", $_.title )
$writer.WriteElementString( "link", $_.link )
$writer.WriteElementString( "author", $_.author )
$writer.WriteStartElement( "description" )
$writer.WriteRaw( "<![CDATA[" ) # desc can contain HTML, so its escaped using SGML escape code
$writer.WriteRaw( $_.description )
$writer.WriteRaw( "]]>" )
$writer.WriteEndElement()
$writer.WriteElementString( "pubDate", $_.pubDate.toString( 'r' ) )
$writer.WriteElementString( "guid", $homePageUrl + "/" + [guid]::NewGuid() )
$writer.WriteEndElement()
End {
$writer.WriteEndElement()
$writer.WriteEndElement()
$writer.WriteEndDocument()
$writer.Close()

$feedItems | New-RssFeed -path "c:\temp\Inboxfeed.xml" -title ($MailboxName + " Inbox")
But it is a Exchange Management Shell script an we would like to execute it like a .php file.
Can anyone help me with this please?
I would like to thank you in advance.
Kind regards,

Answer 1

That's not a Exchange Management Shell script its just a normal powershell script that uses the EWS Managed API
http://msdn.microsoft.com/en-us/library/dd633710(v=exchg.80).aspx . So you can run it from any workstation or server where you have powershell and the Managed API library installed.
You will need to update the line
Add-Type -Path
"C:\Program Files\Microsoft\Exchange\Web Services\1.2\Microsoft.Exchange.WebServices.dll"    
To
Add-Type -Path
"C:\Program Files\Microsoft\Exchange\Web Services\2.0\Microsoft.Exchange.WebServices.dll"    
    To cater for the latest version of the Managed API.
  You can scheduled powershell scripts to run using the Task Scheduler eg
