Whats the version of Exchange you are running on ? Looks like OAB/Address List has missing/incorrect address. You needs to see below articles based on Exchange version and follow article for resolution. http://support.microsoft.com/kb/905813- Exchange 2003 http://support.microsoft.com/kb/867506- Exchange 2000
