Winmail File Viewer – No.1 app to open winmail.dat files on the App Store! Now updated for iOS 13 and the latest iPhones and iPads.
If this app does not open your winmail.dat file, or you have any questions, doubts, or suggestions, then please contact us using the support link.
Need a winmail.dat file opener, viewer, extractor? This is the app for you.
1 - Why doesn’t this app work for me?
Make sure it is a winmail.dat file that you are trying to open with this app!
a) Files such as just a .dat (not winmail.dat) are special data files (hence the name!), and only the software which created them can open them. They can’t be opened using this app.
b) A .wmv file is NOT a winmail.dat file, even though it looks similar! It’s a ‘Windows Media Video’ file which can’t be opened with this app.
c) An ‘Untitled Attachment’ or a ‘MIME’ file or an ‘.eml’ file is NOT a winmail.dat file, and this app should not be used to open this type of file.
Also be sure to check that your file has downloaded completely on your iPhone/iPad. Sometimes large files with sizes in MB take time to get downloaded, especially if you are on a slow WiFi network.
(App will only work on fully downloaded winmail.dat files.)
If it still does not work, then re-starting your iPhone or iPad might do the job. And if nothing helps then contact us via our support page.
2 - Why does the app show 'This is not a TNEF file'?
Around 99% of winmail.dat files are created using TNEF encoding, and all the 'winmail' apps and software are able to open only these types of winmail.dat files.
The solution to open non-TNEF winmail.dat file has not yet been found, though I am working on it and hopefully should be able to include it in the next app update.
3 - How do I open / view / edit the files which are contained inside my winmail.dat file?
This app will ONLY open the winmail.dat attachment, but for any file contained inside the winmail file you will either need the functions/default apps of your iPhone or iPad OR you'll need to install other apps to open Word, Excel, PDF, large Image files, zipped files, Audio and Video files.
The Winmail File Viewer app is a simple app to open winmail.dat (TNEF encoded) files, so please don’t expect it to do anything more.
4 - Why do I get a ‘Blank page’ when I open the winmail.dat file using your app?
Sometimes there is absolutely nothing inside a winmail.dat file except some kind of formatting, fonts, AVG virus scanner info, voting buttons, email read receipts etc. So, if you get a blank page after opening the winmail.dat file please don’t worry because there is nothing wrong with the app. Still, if you need assistance you can contact us.
5 - Are there any new features planned for this app in the future?
Yes, we will be adding lots of new features and functionality to this app in the future, so please keep using it!
Kindly give good ratings and reviews if you like this app. Thank you. :)

Ratings and Reviews
Just what I was looking for!
This app is just what I needed! I work in consulting industry and get emails from many clients, where Microsoft, in its wisdom, has decided to make attachments unreadable to any s/w other than outlook, i.e. A winmail file.
I love my iPhone, but my boss used to really pressure me to switch to blackberry or windows phone, just so I can access those files in the phone as they come in. Well, guess what, now I don't need to! This app solved that problem for me!
Yes, it is not perfect. You need to read the instructions carefully. It takes a couple of tries to figure out how it works. But once you understand it, it works smoothly! All you need to do is keep your finger on the attachment at the bottom of your email until the little menu pops up, and then just tap the first button. Yes, it is slightly complicated, but once you figure it out, it is very easy, like everything else in the iPhone. It opened 9 out of 10 winmails in my emails perfectly! I hope the developers keep improving this app.
I'm just thrilled that I don't have to give up using my iPhone in a business environment now! Love it!
Super Impressed- Customer Service Especially
When I tried the app, it worked perfectly, but I couldn't tell whether or not I had received all the information that was in the winmail file. I emailed the listed developer, and he responded within a few hours with exact instructions and troubleshooting techniques. It was downright refreshing to receive real customer service-he even offered a refund if I was unable to retrieve my file. Rest easy downloading this app, because you can't lose when dealing with people like Hiren Bhatt. He well earned my dollar and a rare beyond-satisfied review.
