If the inbox is pretty full, clean it up a bit and move emails off the server into a PST file on the local drive. Once you get the size down to a reasonable amount, restart Outlook and try it again.
Another advantage of using a PST file, you can try pulling the email with the attachment down to the local file and opening it from there. See if it has the same problem.
