Outlook 2003: Messages with legitimate attachments don't indicate that anything is attached.

Are these mail messages from all sources, or only specific senders?  MS has a fix here http://support.microsoft.com/kb/830302 for when you are sending emails and the attachments are not visible to the recipients.

Specific senders only. I have the seen the issue you're referencing in Kb830302 before, but this is different. It almost looks like the sender forgot to attach a file - but if you click the forward button to forward the message - the attachment becomes visible in the Forward Message window, and can be opened.

Any possiblity of having one of the senders follow the steps in the article and see if it solves the problem for that sender?  If it does, then you know the problem is on the sender's end, not your recipient.  If not, then we can focus on your recipient's settings.

I'm bumping up the points to 500. Here's the overview again. A couple of clients using Outlook 2003 in an Exchange environment (Exchange Server 2007) are receiving email messages from outside of the organization with file attachments. There are a couple of SENDERS (outside the org) whose messages arrive with the attachments intact - but there is no indication that a message is attached. As a workaround, the local users have discovered that if they FORWARD the message, the Forward Message Window that pops up displays the attachment normally.

I'm led to believe the problem is on the sender's end as well. I'm interested if anyone else has ever seen this before. There doesn't appear to be a lot of info on the web about it - but I'm still looking.

Thanks for your help michko.
