While this app does what it promises and opens the files, the previous version kept the file converted imbedded in the email making for easy access. Currently you have to save the document to your downloads to retrieve to subsequently view.Otherwise a very good app.

Worth Buying
Riley WK
After trying a variety of free tools, none of which worked, I stumbled upon this software. It's annoying to have to pay for something so seemingly mundane, but this app works very well. Would recommend.

It Actually Works!

Unlike other winmail opening apps this one actually works. I was hesitant to pay for an app to open such a specific file type but this was well worth it. I use a mac and it works flawlessly!

Cool, except…doesn’t seem to do apple calendar attachments
MatthewGuiste
Functionally great, and pulled the text out of a winmail attachment just fine. However, the one thing I really needed it to do was also extract a meeting invite and let me accept it in Apple Calendar. It doesn’t seem to do that???
