Because I couldn’t quickly find a good script/tool to make a report of my Public Folders that includes a complete drilldown including if they’re mail enabled, what email addresses it has, who has rights on the folder and what size the folders are, I’m sharing this script with you 🙂

Edit: added support for Exchange 2010, uncomment the correct section and comment the 2007 code if you run this on 2010.
