I have the strangest thing going on here. I have Outlook 2007 / exchange 2003 with the preview pan turned off. No rules...just basic Outlook 2007 setup. A user receives an email and in an inconsistent period of time later, it marks itself as read. It comes in unopened, as it should. and it can stay unread for many minutes. As much as 10. But I swear, the user will go back to his computer after a while and the messages are marked as read! I have watched this firsthand myself. The message never gets opened. I tested it just the other day. Sent a message to it. Sat and watched it, without ever touching the message. Sure enough, it marks itself as read minutes later. ANY IDEAS??
