I am new to this site, so forgive me if I am not following the proper etiquette.
I support a small office of users. We are running exchange 2003 and Outlook 2003. We have one user with an email problem. This user sends and receives emails with attachments from a business partner on a fairly frequent basis.
The problem is sometimes when she receives an email with attachments from the business partner, the attachment is not .pdf as expected. The email arrives, but the attachment is a c.htm file. When you open the file, you see the previous emails back and forth between the two users and a large amount of unreadable code.
This problem occurs when our one user receives the email. They don't have problems receiving emails with attachments from us. (I have been copied on the emails and I see the same c.htm file.)
I am thinking the "code" is the pdf file incorrectly recognized and incorporated into the body of the previous messages and then displayed as a c.htm file. The business partner was using mime and our Outlook user was using rich text or a high fuction mail editor.
The current test
Going forward we are still testing, but now both users are set to plain text. (We are thinking the formatting by both mail editors could be the problem.)
The work around
If the business partner sends the same email to my user's gmail account. The Gmail account doesn't have a problem with the attachment(s), the user then forwards the same note to her outlook email address and gets all the attachments.
The business partner is using Lotus Notes 6. They are telling us we are the only customer having this problem. We are telling them, they are the only business partner giving us this problem.
Both organizations have spam filters and Antivirus solutions as part of their mail environments.
Both organizations have lengthy disclaimers after the emails....
My user has been trading emails with this business partner for years. This problem started about three months ago, around the time we gave the user a new workstation, XP Pro loaded, and had the legal disclaimer added to all outgoing mail.
We had our user check the messages using OWA and a second workstation... the messages still arrive as c.htm.
This problem does not occur with every email including a pdf attachment that they send. The problem seems to happen after the two people exchange several emails and the business partner responds with an attachment.
(So opening the c.htm file is a view into long session of emails on the same topic with replies back and forth)
Email's without attachments do not have a problem coming through to us.
Any suggestions would be appreciated.
I think the formatting of the emails is breaking down after several replies causing a corrpution of the mail attachment.
