Couple of thoughts come to mind. Check with the Web
Administrator to make sure .MSG, .XLS, .DOC, etc. are registered as
MIME types on the web server with the appropriate application to
open them. The Outlook message MIME type is "application/msoutlook"
You didn't mention if the Web server is IIS on a Windows OS
or something like Apache on a Unix/Linux OS? As jaalamlady
mentioned, you may want to tick the box for lowercase filenames
shown in the WebHelp publish wizard's first dialog screen in case
it is UNIX.
Finally, as far as Baggage is concerned, note that the folder
tree structure is displayed in the Project tab's Baggage section.
Be sure your files are in the appropriate folders where your topics
reside to resolve any path issues. You can even click and drag the
particular baggage file on top of your link text to create the
hyperlink. That way you know the path is accurate.
Let us know if any of this worked
