Server is running Server 2003 Enterprise and Exchange 2003 Enterprise. User is running MS Office Outlook 2007.
We are sending an email within a 3rd party software to the user and they never see the email in thier inbox. The firewall sees the emails and forwards them to Exchange. Exchange sees the email and forwards to the information store where it is successfully delivered.
I had the user close that instance of Outlook on her PC and moved to another PC. Same result. I have added her mailbox as an additional mailbox to open in the Advanced tab in my mailbox. I see the emails arrive and about a minute later they disappear.
She does not have a client side rule that is deleting/moving the emails. How can I check to see if there is server side rule that is doing this?
