I had some work done at Staples. Staples e-mailed me the work to review, but I was unable to open the attachment. The attachment was in a "winmail.dat" format. I asked Staples to resend the attachment in .jpg form (like they had a few months ago). They said, We ARE sending it to you in .jpg! They looked on their end, and they told me it's a problem on my end.

I'm running the latest update of Leopard on my iBook G4. Whenever I try to open the attachment, up pops the message, "Safari doesn't recognize winmail.dat." (Or something to that effect.)

Should I change something in my preferences? How can I change "winmail.dat" back to .jpg?

It's not your problem; it's theirs. Those annoying winmail.dat files are generated by people using Microsoft email programs (Exchange, Outlook) who want to send rich text or HTML mail. Their program generates these attachments automatically and non-Microsoft email programs generally cannot read them.

There are programs on the Mac to decode these attachments. TNEF's Enough is the one that comes to my mind. A Google search should show you where it lives. I've not used it in a long time because I usually impolitely ask the sender to learn how to properly use their email program and try again with less parochial settings.



Attachment: smime.p7s
Description: S/MIME cryptographic signature
