WinMail DAT Viewer Pro App Reviews

50 add

Better choices exist but the differences are minor

Right-click (Open With) is a much needed feature.

Works fine so far

Am now able to open winmail.dat files by clicking Open on the attachment in the email (Outlook 2011 Mac). Drag and drop from the email doesn’t seem to work but DnD from Finder does work. Rating a 5 for now as purchase, installation and use went quickly and without any problems.

version 2.2 works on my MacPro

I am using Winmail DAT Viewer version 2.2 on a MacPro. My office at work continues to send me attachments generated in Outlook which won’t open on my Mac. This program works perfectly for me every time. I don’t understand why some of the other reviewers have a problem. I have a 2008 MacPro running El Capitan, but it also worked for me with the previous OS versions.

Bunch of .dat files, says all contain no data

It says all of them have no message body, and no attachments. File sizes from a couple hundred bytes to severl megabytes. Others have opened these files. Doesnt seem right to pay good money to find out the program wont work.

Works as described

Have some clients who send me photos for bidding purposes, on construction jobs. Just couldn’t open them, until Winmail DAT Viewer came along. Always there, always works. Thanks.

Easy to use

Love this little app that converts win.dat files to something I can open on my Mac. Only problem is that if you save the win.dat file to your hard drive, be sure to change the name of the file so that you don’t copy over previous win.dat files if you save them to the same location.

dat files

This app contiunues to open .dat files for me. I have had no issues and will continue using this when the dreaded .dat appears in my in box.

MAYBE it works 25% of the time (at best)

Don’t waste your money! This version may be better than it was, but it’s still “JUST NO DAMNED GOOD!” - at least not reliably so - at all!

Saved the day!

This app saved the day for me. I work at home and every attachment from my employer came through as a winmail.dat file. This $2 app works every time. I don’t know what I’d do without it! Thank you!


It sorts out in the simplist way a very confusing and annoying winmail.dat that no one seems to have control over as it gobbles up the attachments to e-mails. I give it a 5 star with thanks for letting me receive attachments.

Best Ever!

WinMail.DAT challenges have been the bane of my existence. I have tried every solution out there. None come close. The WinMail DAT Viewer Pro is the best ever! Thanks to whomever developed it. Good job.

Don’t do it!

Won’t even open! Thanks for nothing.

not at all useful

woooooooooow This app literally does nothing. It doesn’t open winmail.dat files….it just tells you to buy the full version, which is utterly and insanely expensive, which no person in their right mind would ever buy, ever. RUN AWAY

Doesn’t work

Click on it and nothing happens. Three bucks down the tubes. Apple should do a better job of vetting apps.

does what it says it will

just installed the app; works great; well worth the $1.99. thank you.

Works great

Nicely done. Always works great

Love it!

I’ve struggled with winmail.dat files for years, having to ask colleauges with different systems to access the files for me. Now I’m all set. LOVE this app!

Poor Application.

Purchased this app to read win mail.dat files and the first attachement I tried, it states that it does not support PDF files. Most WINMAIL.DAT files I receive are PDF files. This product does nto support most WINMAIL.DAT files. Very disappointed. How do I get my purchase price refunded?

Not Working for me

Bought this app looking to solve the problem of receiving winmaill.dat files from client using PC’s and outlook, but it is not working for me, have tried to open many winmail.dat files and none work.

Unable to open winmail.dat

Something is not working. Perhaps I need a tutorial program. Help! Winmail Viewer opens nothing for me.
