A Great Tool For Opening the Occasional winmail.dat File - This app does exactly what I wanted. On rare occasions, I get a winmail.dat file attached to e-mail from a PC user. I save the attachment to my desktop, open it with this application, and boom ... I can open the attachment in the appropriate Mac application. It works great. Unlike some other reviewers, I do not want a plugin. I don't want to install a Mail bundle (and the trouble that spells every time Apple updates that is always installed on my system for the few times I encounter winmail.dat files

Does nothing of value other than telling you to buy the full version. - Pretty sure the positive reviews for this were manufactured by the software company, as this application does nothing and simply displays “buy the pro version” for it to actually do anything.

Review by Houstonsaudi

Grateful for this app - I’m not necessarily tech savvy. I happen to be working in the MIddle East and received an important winmail attachment that I was unable to open on my Macbook. Within minutes, I downloaded the app which I found in the App Store and was successfully able to open the document. It was easy and worked as it was supposed to. Thank you!

Simple solution - I’ve only needed this a handful of times, but it’s an indispensable tool for me. It’s super simple, and reliably converts emails saved in formats that my Mac can’t otherwise read. I’m a happy user.

Required Review - I would probablly give this program a much higher rating. However, by forcing me to rate your program you make me lower that rating down to nothing. It is my choice whether to rate a program or not. Let me use and try it out and then rate it.

Review by Disgusted123456789

Took Over My Computer Screen - I have not purchased this, and it took over my computer screen. I couldn’t get past it without rating it. Give me a break! I’d like to give it zero stars. Why should I have to rate something I haven’t even had the opportunity to use? Plus taking over my monitor did not make me happy! My time is valuable, and you have wasted it!!!!!

Very Handy - When I get an attachment that I can’t open on my phone or tablet, I breathe a sign of relief and think, “That Letter Opener app will open it on the mac.” It always does.
