I looked into header of Outlook auto reply emails but didn't find any special. You can try a little trick here - Just keep track of time at which your mail server sends out the mail to users. If the mail server receives a reply mail within few seconds (say less than 10 seconds), its probably an auto reply. Incorporate this with subject parsing to get better detection of auto reply mails. Its not a concrete method but I guess it will work.
