We have an extensive number of files on our file server that were created by dragging and dropping from the MS Outlook client to Windows Explorer.  (Tens of thousands of items in thousands of subdirectories.)  MS Outlook has been removed from the PCs of some users who need access to these *.msg files, and will not be reinstalled.  We must find a viewer to open the .msg files, and also be able to extract / view the attachments.

Can I use TheBat! for this?  I downloaded and fooled around with it, but cannot get it to work.
