Experts, please help.
We have Exchange 2003 as mail server. One of our client running windows XP Pro with Office 2003 Pro is having problem receiving email from one internal address call firstname.lastname@example.org. The training_system automatically send out notice email every day to a mail distribution group included the problem user. Every other user in the group receives the training_system email but the problem one. All user in the same group has exactly same permission. There is no mail forwarding, filtering or any redirection setup. On the client machine, there is no rule or any block list configured in outlook. This is what gets really strange, I have tried open user's Inbox from server before she comes in and verified that user's Inbox received the training_system email. As soon as user turned on the computer and opens up Outlook on the local machine, the training_system email is no where to be found. I am not a Exchange expert and couldn't figured out what cause the issue so I recreated user's mail box, distribution group, rejoin user to group, recreated user's .pst file, reinstall Outlook just to see if I have any luck before I complete delete this user and recreate account and still don't know why the one single email is missing every day on one user in the group. Please help and thank you in advance.
