Simply changing the file extension from tiff to pdf doesn't make it a
pdf-file; it would turn it into a tiff-file with the wrong extension.
If the scanner has an option to scan it as a pdf-file instead of as a
tiff-file, use that. Otherwise you'll need a conversion application which
can turn tiff-files into pdf-files. But then again; why is opening a
tiff-file so bad for this user?

Either way, this is not an Outlook issue. Check the documentation of the
scanner to see if it can scan documents as pdf-files.

have an associate who uses Office 2003, is scanning docs from a copier and
sending them via his email address. no trouble receiving the docs, but
they
are opening with Window picture and Fax viewer. I tried saving the image
as
a .pdf to the desktop, which it did--but when he tries to OPEN the pdf on
the
desktop, it says something happened or is missing from the file when it
was
saved from Outlook. i scanned the image and sent it to my computer, the
forwarded the pdf to him, and it opened fine. I am not having the same
issues he is, is this unique to Office 2003, (I use 2007) or is there a
setting that needs to be adjusted?
