## What is Winmail Reader?

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.dat files are in fact TNEF format (Transport Neutral Encapsulation Format). Microsoft Outlook e-mail program for Windows send e-mails as TNEF.

The easy-to-use solution to circumvent this problem is provided by Winmail Reader.

### 5/5 — Excellent

*2022-04-12, version 4.0*

I just downloaded this app. It worked immediately on a winmail.dat attachment sent to me by someone trying to be oh so superior by refusing to send as a pdf!
No worries, this opened their attachment instantly.
BUY IT! ITS CHEAP AND EFFECTIVE!

### 1/5 — Don’t waste your money

*2022-03-26*

This doesn’t work and you can not even get a refund

### 5/5 — Worth every penny

*2021-11-09, version 4.0*

I tried a couple of “free” readers only to find it would cost me hundreds of pounds to read the amount of files I needed to. This one is so simple to use and a one off cost which is so inexpensive compared to the “free” readers I tried. I can’t recommend this app enough, so easy to use and exceptional value for money. I really hope you’re convinced because you won’t regret it if you buy it!
