Does exactly what it says it will do

As a mac user in a company that runs primarily windows, after searching for .msg viewers, trying a few online converters, downloading a few of the “dat viewers” here in the store that didn’t show me any msg content, I went ahead and pulled the trigger on this paid app (knowing it's possible to request a refund from Apple if it didn’t work effectively). Worked instantly showing exact content of msg files and all marketed features work for me. It will support my particular needs and am grateful there’s a reasonably priced option here to mitigate the steps of seeing the file content.

Only recommendation I’d have for the developer is to replace the toolbar button icons with something more modern, reflective of Apple’s evolving aethetic. The present icons (in version 1.9.6) look like clipart and it lessens the perceived quality of the app itself.

Fantastic, works perfectly.

I received 4 .msg files that someone had saved from Outlook. This app was able to quickly open all 4 and save them as pdf's, it also allowed me to save attachments from those emails(1 pdf, 1 rtf file).

Saved me a bunch of time and for $5 I have it available in the future if needed.

FYI- The two negative reviews I saw made no sense and one appears to be deliberately misleading. I reported the second one to Apple.

This application just flat-out works. I'm amazed. It handles attachments, etc, just like a native email client. I can save-as and print and reply. All envelope information is retained, including To, Cc, etc. It's worth 10x the $5 pricetag. If you need it, get it. This is the one.
