So whenever we receive PDF attachments on this OS X desktop running Leopard and then we made the upgrade to Snow Leopard, Lion and then finally Mountain Lion, we continue to have problems with PDFs turning into Winmail.dat files even with Apple Mail and Outlook 2011.  We've made sure that the emails are being sent in HTML and not rich text.  Any other ideas?

Changed contact info to only send in plain text but would like a better solution if one is available.  We do not wish to use any third party programs to read the winmail.dat either if at all possible.

This worked for me recently...

The attachment means the email was sent from a Microsoft email application (such as Outlook and the Microsoft Exchange Client) and includes rich text information--how fonts, colors and specialized attributes such as underlining or boldface should appear in the email (the attachment doesn't appear in Outlook but does appear in Mail; it may appear in other email applications as a MIME section named "application/ms-tnef")
Avoiding these attachments

To avoid seeing these attachments in the future, you ask the sender to deselect the email's "Send to this recipient in Microsoft rich text format" checkbox or preference setting in mail client before they send the message.
