I received an excel spreadsheet in an email and updated it over
several days frequently "saving" it. I exited Excel, later restarted
it, and when I tried to reopen the file, it was no where to be found.
I looked in the Excel autosave and default file locations. Are there
any other places where I could look?

If you're lucky, it will still be in the Outlook Secure Temp Folder.
