## What is Winmail Reader Lite?

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. 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.

### 1/5 — Lite-Version, die überhaupt nix kann.

*2024-07-08*

Völlig sinnfrei ist es eine Lite-Version anzubieten, die über null (!)Funktionsumfang verfügt. Weder kann ich Anhänge öffnen, geschweige denn dass die mir überhaupt angezeigt werden. Das ist derart unseriös dass ich den Kauf der „Vollversion“ nicht in Erwägung ziehe. App sofort wieder gelöscht.

### 1/5 — Don’t bother

*2023-04-21*

It doesn’t work for the intended purpose. It is probably spyware. I removed it after the first use. You can buy the full version for 1.99 a month. I wouldn’t after my experience with the lite version. Most other software worked for me to open the winmail.dat file

### 4/5 — Funktioniert gute …aber

*2021-01-18*

Die App funktioniert tadellos,  allerdings ist das kostenfreie  Download nicht funktionsfähig. Das ist nicht die feine englische Art. Die Autoren werden dringend aufgefordert preisehrlich zu sein. So gehts nicht. Dann gibts auch keinen User-Frust. Und die ca 2,00 Euro ist die Applikation locker wert.

### 1/5 — Deceit, not free!

*2019-10-12*

deceit, charge to use after downloading

### 1/5 — Not worth it

*2019-06-03*

Spent the $1.99 but the app crashes when I try to save my photos to my photo album. Worthless.

### 1/5 — Deceiving App. “Lite” version does nothing.

*2018-12-14*

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.

### 1/5 — Scam

*2018-10-30*

I like to try versions before buying.  The free version does nothing.  This app should be removed from the store.  Totally dishonest.

### 1/5 — OMG

*2018-10-19*

This app does not work. It’s a trap

### 1/5 — 最悪最低使えません

*2017-04-27*

使えません

### 1/5 — Ne sert à rien...

*2017-01-30*

Obligation de payer pour ouvrir les fichiers. Même pour un essai !
