Form design question

Customer created a form that has a 3mb Powerpoint attached to it. The form
size limit kicks stating basically too large. I can go in and change the
size on each Outlook to accomodate the form but that would be touching alot
of systems.

So my questions are - can size requirement be change globally so that when
someone opens the form it automatically accommodates the needed space.

Another option instead of having a 3mb ppt file in the form is there a
better way to do this so they can access the file with out such a large file.

Thanks all
