Excellent

I just downloaded this app. It worked immediately on a winmail.dat attachment sent to me by someone trying to be oh so superior by refusing to send as a pdf!
No worries, this opened their attachment instantly.
BUY IT! ITS CHEAP AND EFFECTIVE!

Don’t waste your money

This doesn’t work and you can not even get a refund

Worth every penny

I tried a couple of “free” readers only to find it would cost me hundreds of pounds to read the amount of files I needed to. This one is so simple to use and a one off cost which is so inexpensive compared to the “free” readers I tried. I can’t recommend this app enough, so easy to use and exceptional value for money. I really hope you’re convinced because you won’t regret it if you buy it!

FAQ

What is a winmail.dat file?

A "winmail.dat" file is an attachment sent by Microsoft Outlook when configured to send emails in TNEF (Transport Neutral Encapsulation Format). Many email clients, unlike Outlook, do not understand this format, leading to an unreadable attachment.

What can I do with the winmail.dat file using this app?

This app decodes the "winmail.dat" file, allowing you to view the original email message, extract all attachments, preview them, and then save, copy, print, or share these attachments. You can also resend the entire decoded email.

Can I add appointments or contacts from the winmail.dat file?

Yes, the app can create and add Microsoft Outlook Appointment and Meeting information to your iOS Calendar. It can also read embedded notes and create/add contact address cards directly into your iOS Contacts.

Is this app compatible with my iPhone or iPad?

The app is designed for iPhones, iPads, and iPod touch devices. It leverages iOS features like Quick Look for previews and AirDrop for sharing to nearby devices.

How much does this app cost?

This application is a paid app, meaning there is an upfront cost to download and use it. It does not feature in-app purchases or advertisements.
