What is a winmail.dat file?

Winmail.dat files contain email messages from Microsoft Outlook. Since iPhones, iPads, iPod touch devices and Macs can't read them natively, users have to rely on third-party software such as Letter Opener to convert and open them.

What is a ZIP file?

A ZIP file may contain one or more compressed files or directories. Letter Opener can open ZIP files and give access to the files inside.

Great for work!

I use this app regularly for work. I didn't know it had a video tutorial on the App Store or I would have gotten it sooner. Really helpful! Thank you!
