Are your clients/friends/vendors sending you Exchange Rich Text winmail.dat producing emails? Do you think they are always sending you attachments even when they’re not? If you don’t want to push the issue and have them mark you in their address book as not being able to accept Rich Text emails (even though you can, just not theirs). Then you can turn to this little new found gem called “TNEF’s Enough” by Josh Jacob. I’ve tested it out and it was able to see and retrieve multiple embedded files out of those pesky little winmail.dat files. Keep in mind that not all of these files contain attachments, as I understand it also holds the formatting info for the email. If this article has helped you please share it with your other Mac and non Exchange using friends.
