This is on Exchange 2003 SP2 Standard Edition.
A user will log in to OWA and browse through their email, when they select certain emails the preview pane will show a 404 error. If they open the email to read, reply or forward it a new window pops up with a 404 error. If the user logs into OWA on a different computer and checks that message the result will be the same. This happens to all users, for apparently random emails. Sometimes the emails are internal, sometimes they are external. Sometimes they have attachments, sometimes they don't.
Any ideas?
