Outlook Power Tool 2007 for SharePoint
Haven't tried this myself so would welcome any feedback .. .. ..
SharePoint delivers plenty of functionality out of the box that enhances the collaboration experience. The ability to Send Links of documents directly from the interface is now provided out of the box. However, this functionality is limited to only one file at a time.
This FREE tool from echoTechnology will allow you to select multiple documents from your document library send links and document attachments via your default browser.
The download includes the code and instructions for installation. This feature works for SharePoint 2007 (WSS and MOSS).
