I found this via James Senior and if you're running Outlook on Vista it's a must have. Quite simply, if you like the way Outlook 2007 previews document formats like Word, JPEG and others you can now do this with PDF. Tim Heuer who developed the fantastic Flickr plugin for Windows Live Writer has worked with Foxit to produce this PDF preview viewer for Outlook 2007. No more explanation needed - it does what it says on the tin!
