Solved a fundamental issue with my Mac - Outlook users can hardly open a winmail file. So, I'm extremely happy that this is solved now with this tool. It really works fine on my Macbook. I also appreciate the very precise description. Ok, it's not as seamless as click-and-open. But that has not been my priority and I acknowloedge the tool has just done it's first step. Five stars and a big thank you to the developer.

Did not work at all. - I tried this app on over 10 different winmail.dat files, worked on 1. Most gave error message: The document “winmail-47.dat” could not be opened. That TNEF format file does not have any attachments.

Winmail did exactly nothing - I downloaded Winmail viewer to a MacPro OS 10.10.5. When I tried to get it to work with a winmail.dat file, all it did was show a blank folder. No text & no graphics. A total waste of time.

Perfect winmail viewing tool! - I am happy to get this tool, it is pretty easy-to-use and highly-efficient, I can quickly open multiple winmail dat files from my clients, and what makes me surprised, I can easily save the important files onto desktop folder.

Good, Keep go on! - I like it for some time, it helped me read lots winmal .dat files from my customers and did perfectly every time, and helped me save much time to view files. And this time, it gets upgraded again, it is good, I download and try it today. I hope Enolsoft Winmail Viewer has better future, and brings more benefits to us.

Version 3.1.0
Review by Jeantet

This is the one. - I’ve looked at several of these winmail.dat viewing apps because I do a lot of work with an organization that is standardized on Outlook’s / Exchange’s rich text platform. While all these winmail.dat apps can extract attachments, this is the first one I found that *also* can show me the rich text of the actual email. That’s a big deal for me because I’m constantly receiving large tables, and all the formatting is lost when MacMail and Thunderbird handle the messages by converting them to plain text. So I’m giving this app 5 stars because: 1. it can do attachments *and* display the rtf of the message 2. Clean interface / easy to use 3. no click-baity try before you buy that basically doesn’t work unless you pay and then find out it only does attachments and not rtf 4. less expensive than most of the others 5. just works consistently, no headaches. Thank you for a great app!
