Do you ever receive emails with winmail.dat files on your Mac? Windows users send them to me all the time. These files are windows formatted Microsoft Outlook email attachments and one of the rare file formats that your Mac has no idea how to handle. I get winmail.dat files too often, and I finally found the right app for dealing them with Letter Opener.
Letter Opener converts and displays the content of winmail.dat files automatically inside macOS Mail so that they appear just like any other email. With Letter Opener, you will never have to think about winmail.dat attachments again. Letter Opener is fully localized in Arabic, Cat, Chinese, Dutch, French, German, Hindi, Italian, Japanese, Korean, Portuguese, Russian, Spanish and Swedish.
I love Letter Opener because, since installing it, a long-time problem just went away. Now I'm barely even aware of receiving winmail.dat files because everything is taken care of right in Apple Mail. And for you mobile warriors, there’s also an iOS version.
