Matthew,
Unless you are trying to send a Project file to email (File > Send To,
Mail recipient (as attachment), I suggest reposting your question to
the Outlook newsgroup. If you are trying to send a Project file,
please be much more specific -- what version of Project, including
service pack, and specifically what happens when you try to send the
file as an email attachment.
I hope this helps. Let us know how you get along.
