Though Mac users we may all be, the rest of the world doesn’t necessarily share in our enlightenment. We still live in a Windows world, and that means dealing with certain Microsoftian annoyances. Take email attachments, for example. Ever gotten a forward from a friend asking you to check out a knee-slappingly hilarious attachment? Eagerly anticipating a single bright spark to your otherwise dull existence you scroll down and find…an impenetrable “winmail.dat” file.
Winmail.dat files come to us courtesy of Microsoft Outlook and Exchange users. Encoded as rich text, these files, which have a MIME type of application/ms-tnef, are pretty much useless to anybody who doesn’t run Outlook.
Boooo. Yes, you could reach out with the power of the Force and strangle your correspondent to death, but that might just be a wee bit overreactive. Instead, try Joshua Jacob’s TNEF’s Enough. This one-trick pony application lets you open up winmail.dat files and save the attachments secreted within. Works like a charm (just used it myself yesterday) and it’s freeware (donations welcome).

Was having problems with winmail.dat files a while back and everything on the net points you towards TNEF's Enough. It did open the file and split it into 2 parts but neither part was of any use. Doesn't always give you a readable file!
The Apple Mail Plug-in OMiC also process this Microsoft Outlook winmail.dat files.
