Ahh, the infamous winmail.dat files,

Don't you just love Microsoft! (Rhetorical, no answer required)

The problem is caused by Outlook decided which format it is best to send emails in.

Outlook can be configured to prevent this happening, so if it keeps happening to you with emails from the same person, direct them to this site:
http://email.about.com/od/outlooktips/qt/Prevent_Winmail_dat_Attachments_from_Being_Sent_in_Outlook.htm

Meanwhile, just pop over to this site: http://mac.softpedia.com/get/Utilities/TNEFs-Enough.shtml
and download this little utility.
Follow the instructions and you will be able to open and read the email.

Let us know how you get on.

I downloaded the file for 10.5 and above, but when I try to open the winmail.dat file nothing happens. Is it compatible with 10.6.2 I wonder? Thanks for your suggestions.

try this:
On the email with the offending winmail.dat file, save that attachment to the desktop.

Launch the TNEF application, it works on 10.6.2, and choose Open from the menubar at the top of the screen.
Navigate to the desktop and choose the winmail.dat file that you saved there.

Any better?

Of course, you may have already done all of the above. In that case, sorry.

this is the result of my research on these files:

winmail.dat is a windows-only file that often gets sent over exchange server accounts. It doesn't contain any useful info for a Macintosh mail client because you can't follow the data back to the source from your computer. winmail.dat files can only be received by other Microsoft Exchange users. No one else can view them without additional software or having the Exchange user reconfigured.

Sorry, I don't have the source. Might've been Wikipedia.

Thank you again. Well I followed your instructions but when I click on the winmail.dat file I get a box in the upper left of the screen entitled "winmail.dat:." Below that "embedded files" and beside that "attributes". Below in the box: b

and without that .dat file it is almost impossible to find out.

If you really want to know, you could email it to me, email me via my profile and let me know.
