Winmail Reader is ultimate tool for reading "winmail.dat" attachment files on iPhones, iPads and iPod touch. Winmail Reader decodes "winmail.dat" file, and allows any attachments contained in them to be opened, read, saved or e-mailed.

* * * Winmail Reader for Mac is also available on the Mac App Store. * * *

Winmail.dat files are in fact TNEF format (Transport Neutral Encapsulation Format). Microsoft Outlook e-mail program for Windows send e-mails as TNEF. Most other e-mail programs, including Mail, do not understand TNEF. If your e-mail program doesn't understand TNEF, you may only see an attachment named "winmail.dat" that you cannot open. The easy-to-use solution to circumvent this problem is provided by Winmail Reader.


◆ Decodes "winmail.dat" files and list all attachments contained in it including email message.

Purchase needed for attachments

Just as a previous review stated, you have to purchase the upgrade in order to be able to open attachments. Description is misleading...

Deceiving App. “Lite” version does nothing.

Downloaded the app to use the “lite” version thinking it would work. It does not work at all. It takes you directly to the screen which asks you to purchase the “full” version. It is a very deceiving app. The only thing it does do is tell you what type of file that was sent to you. Don’t waste your time.

Absolute garbage

Doesn't do anything at all. No "open in" button. Can open as pdf, but only if you upgrade. Does not read anything at all unless you upgrade. Absolutely worthless without upgrade. Free version just a scam!
