Reviews

There’s no fuss with Letter Opener, no need to drag the winmail.dat file onto another application or call upon several programs to help you. Once Letter Opener is installed, you can forget about it.

Outlook compresses all of its attachments together into one winmail.dat file, leaving the rest of us scratching our heads as to what's inside. With Letter Opener the attachments appear like any others!

What a relief! This solves a recurring problem, that was a major irritation! It works flawlessly and seamlessly. You never even know it's there!
