We are getting delayed delivery messages on our SBS 2008/Exchange 2007 box. Most users are not having any issues and mail is working as expected. Some mails are getting a delayed delivery error. 4 of the 15 users have reported the problem.
We have checked the queues and the messages seem to have been sent. There do not seem to be any DNS problems
Is it possible that the delay/ timeout for sending the error message is set to too short an interval and if so can this be changed?
