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.

FEATURES
- Open winmail.dat and MSG files and convert Microsoft Outlook appointments, notes, contacts etc. to macOS native formats.

- 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.

SUBSCRIPTION
Open unlimited files of all supported file types with the Letter Opener Subscription.

Works Perfectly

The thing I want in a program like this is that it just plain ol' works without me thinking about it. This program solves the problem I've had of PC users sending me attachments as dat files that I couldn't open on my Mac. Now I can. The developer even proactively reached out to me to see if I was having any issues. Pretty great customer service, I'd say.

Letter Opener Gets My Vote

Letter Opener Gets My Vote for being a great program. I have used it almost every day for the past 3 years and have not had any problems. I receive pdf & other files all day long from window users & have never had a problem opening the files. I highly recommend it!

works great

this application works great. i often get attachments from PC users in that dat format I can’t open/read on my mac - this solves that problem like a charm. it was easy and fast to install. also you aren’t taken to another screen to open attachments; it’s seamless—you just click on it and it opens.
