Once in a while he'll get an error when trying to send to a person on the same server he's on. Error below. These errors come at random times. I've tried to check in the app log and I can't find anything that shows me an error occurred at the time of the attempted email transmission. The only weird thing is that these two users reside on the same server, same mail store. The following recipient(s) could not be reached: End User on 10/25/2006 7:31 AM The message could not be delivered because the recipient's destination email system is unknown or invalid. Please check the address and try again, or contact your system administrator to verify connectivity to the email system of the recipient. <domain name #5.1.2> Thanks, John B. ------------------------------------------------------- List Archives: //www.freelists.org/archives/exchangelist/ MSExchange Newsletter: http://www.msexchange.org/pages/newsletter.asp MSExchange Articles and Tutorials: http://www.msexchange.org/articles_tutorials/ MSExchange Blogs: http://blogs.msexchange.org/ ------------------------------------------------------- Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------- To unsubscribe visit http://www.msexchange.org/pages/exchangelist.asp Report abuse to listadmin@xxxxxxxxxxxxxx
