Description
Open Winmail.dat, MSG and XPS files with just a double-click.

ABOUT
A winmail.dat file is an email from Microsoft Outlook that can not be read by other email applications. It needs to be converted for the content to be accessible.
Letter Opener does that with a simple double-click!
With 10 years experience (and a special dislike for winmail.dat files) we made sure that working together with Microsoft Outlook and Windows users can be simple and seamless.

- Convert Microsoft XPS documents to Adobe PDF files
- Quickly view the contents of a Winmail.dat, MSG and XPS file with a tap on your space-bar via Quick Look
- Once extracted, files can be treated like any other file on your computer
Letter Opener speaks your language! It’s fully localized in Arabic, Chinese, Dutch, French, German, Hindi, Italian, Japanese, Korean, Portuguese, Russian, Spanish and Swedish.

Ratings and Reviews
Perfect and affordable solution
I am currently going to university doing my master’s degree and any communication between me and my professors with an attachment comes to me as win mail.dat, which my Mac cannot open. This program works in a painless way to access these files. In 2019, it seems ridiculous that I should need an extra app just to open emails, but at least this provides the perfect solution.
Simple and inexpensive solution to a common need
A simple and inexpensive app to solve a common need.
I had my files open about 3 minutes after I found the app.
It came recommended, it was quick to download, quick to install, and the interface is so intuitive I didn’t even look at the instructions.
Worked on all the .DAT files my client sent me.
Even has a free trial — so I got to test it out before I paid.
All round good experience.
Simple solution, works well
This is the best fix around for the PC to Mac attachment issues. It's easy to download, works automatically within Mac Mail as soon as you click an attachment, opens the file quickly and is a great work-around to a problem that shouldn't exist, but does, and is super annoying to deal with.
Cheaper than signing up to pay for Microsoft suite.
