I have a Purchase Order Requests list with an excel spreadsheet setup as a default content type so users can fill out the PO and save it to the list. My problem is, some of our users are not being co-operative and are saving the file to their desktop, so they can edit and print PO's, and are not bothering to save them to our SharePoint 2007 server. What I am looking to do is prevent the users from being able to save the documents to any other location other than a SharePoint list. And even then, prevent them from being able to copy the file from SharePoint to their computer if they happen to map the list as a drive to their computers. How do I go about doing this?

Hi, I understand that you don’t want users to download or copy a spread sheet to other places except the SharePoint list .You can use Windows Rights Management Services(RMS) to protect your files by deploying it with SharePoint . Windows Rights Management Services is used for restricting access to rights-protected content to authorized users only. For more information about RMS ,please refer to these sites: Window Security.COM: http://www.windowsecurity.com/articles/Windows_Rights_Management_Service_Documents.html Deploying Windows Rights Management Services with Microsoft Office SharePoint Server 2007 Step-by-Step Guide: http://blogs.msdn.com/b/johnwe/archive/2007/05/16/deploying-windows-rights-management-services-with-microsoft-office-sharepoint-server-2007-step-by-step-guide.aspx Thanks ,Regards, Rock Wang Microsoft Online Community Support
