|re: "It did not show up in my default directory for saving files from within Word."|
I use Outlook at work. If I open an attached document directly from an email and then accidentally Save it (Save, not Save As) Word leaves it in the folder that Outlook downloaded it to, which is folder only it (Outlook) seems to know about.
To find it, what I do is this:
Open the document from within the email again.
Choose File...Save As.
Note the location that Word wants to save it to.
That's probably where you'll find the file you are looking for.
