Looking to open those frustrating Microsoft Outlook MSG, OFT, and Winmail.dat files on your Mac? We've got you covered.

MSG files are often generated by the PC version of Microsoft Outlook. This proprietary format is easily read on other PCs, but it is unrecognizable on Macs - even if you are using Microsoft Outlook for Mac or Apple Mail. MSG Viewer for Outlook works like magic by converting the unrecognizable format into the email that your friend or coworker intended to send you - and it all happens in a split second.

With this easy-to-use program, you'll be able to open all of those MSG files seamlessly in your favorite Mac email clients. Batch processing and conversion of Outlook MSG contacts (.vcf) is also supported.

The free version only converts selected portions of the MSG file. The licensed version (available via in-app purchase) activates all features, including complete conversion of MSG files and batch processing.

FYI, free trial is limited to 3 emails

converted 3 files, which was great. but free trial stopped after 3, only showing the header and a couple lines.
I only have 10 emails to view, so not worth it for me. But if you have to do this regularly or for a lot of emails, might be OK

Helps me deal with absurdly ridiculous forms of communication

Some of our clients send attached .msg files instead of just, you know, sending an e-mail. This helps all of us at the office deal with antiquated file types used only by technologically-illiterate individuals.

Works well

Just installed it today and tried it. Did not install the ‘preview’ component off of the web, but just dragging and dropping a .MSG file to the viewer window did work! Nice to have something handy like this.
