sometimes, pp shows
are very large and some
isp's have a size limit
for sending emails with
attachments.

so if your file is too large,
which it may likely well be
because of the graphics,
embedded fonts, etc,
your email will be
rejected.

however, what you want
might want to try is
to save the show as a
file in a folder then try
sending it to yourself
as a pps or html to see
how successful it will
be for you.

here is some more

Change the file extention to *.pps

That will open the file as Power Point Show. This assumes the receiver has
PP installed as an application.
