I was looking for a single app that could handle all the weird files I get from my Windows-using colleagues—DAT, MSG, and even XPS. This viewer is the perfect all-in-one solution. It's clean, fast, and does exactly what it promises. I can now view, extract, and save attachments without having to ask the sender to resend the email in a different format. It has saved me so much time and embarrassment. Highly recommended!
Excellent winmail viewer
