I am having a strange issue. We have half the users on Exchange 2003 and half on Exchange 2007 connected via SMTP connector. I am part of a distribution group: firstname.lastname@example.org. There are other members of the same DL. Some of the members are from E2K3 and some from E2K7. I get all email addressed to this distribution group, except for one. We have a script that runs and generates an email with data. Only users that are on Exchange 2003 are receiving this, but any of the users that have a mailbox on Exchange 2007 are not. If I look at tracking, I do not see this message in the message tracking. I am not asure where else to look. Could this be getting caught in the server as junk. if so, where do I look?
