We are using Exchange Server 2003 and all users have Outlook 2003 and Outlook Web Access. A client addresses an html format e-mail to two of our users. For one user, the body of the e-mail is normal. For the other user, the body of the e-mail is an attachment whose name matches the subject line of the e-mail. It's not a .dat attachment. If I try to save the attachment it, it defaults to type "message file." I looked at the headers of the e-mail in both users' mailboxes and noticed where one has "Content-Type: text/plain;" the other that is making the attachment has "Content-Type: message/rfc822." I don't know if that's of any significance.
I haven't been able to find a setting between the two user accounts that might cause this condition. Any ideas will be greatly appreciated.
