While troubleshooting an issue I stopped and retarted the exchange services on a 2003 Small Business server. Almost immediately the users were complaining that undeliverables were showing up in outlook. A short time later replies were being sent asking why they were receiving old emails. They are not being sent out by the user's PC's but from exchange. What should I be looking at first?
Thank you for your response. The article covers the NDR's but is a little vague about the email that were sent out. Some are much older than a few days. Would this still apply?
