We have been receiving Page Not Found errors reading certain messages in OWA (Exchange 2000). It appears that when the subject line ends in a series of dots, the message is displayed. The messages are completely readable in Outlook. I believe this has to do with the filename extension being attached to the subject line. Has anyone had this experience? Is this a known issue? Is there a solution, other than asking people's correspondents not to use dots in a subject line?
