1. 5/5Works great - with templates too!

   My employer only distibutes and supports Windows-based computers but allows employees to BYO computers and devices, so long as the Microsoft MDM/Company Portal software is installed. As a avid Mac user, I've struggled when provided with customer-facing email templates from Marketing in the windows .oft format. Using Msg View Pro, I can now open those .oft files (Outlook for Windows email template files), save them to .eml format (Outlook for Mac message file), then open that message in Outlook for Mac and "Save As Template" from the file menu. And it works perfectly without any formatting disruption to the original template, including any embedded HTML graphic links. Maybe one day the developer of this app will include a direct export from .oft (Outlook for Windows email template) to .emltpl (Outlook for Mac email template) but I'm satisfied with the present solution even with having to take the extra step and do that myself. It's a very minor inconvenience. I'm thrilled I no longer need to ask a Windows user colleague to open the template, address the email to me and send back, and then clean up the file and save as a Mac-friendly template. Saves me from the delay, all the clean up, and of course prevents me from having to inconvenience others. One would think Microsoft would have gotten past this incompatibility by now like they have with most other office files that open seamlessly across the two OS platforms.

2. 5/5Does 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.

3. 5/5Exactly what I needed

   I have an MSG attachment in a Jira ticket from a Windows user. I need to view the screenshot that was included in the MSG attachment. I can't open it in Outlook or Mail, and head in Terminal simply outputs garbled data I can't make sense of. I run this app and presto! I can see the contents. The screenshot isn't inline with the email content, but couldn't care less—I need the content. The screenshot image file is included at the bottom of the converted email's window as an attachment. I double-click it, view the screenshot and now I can understand the user's problem. I fix the problem, update and close my Jira ticket. Only $5 and still in active development. Thank you!

4. 4/5You have lots of choices. Just buy this one.

   I work with Windows users and am often asked to look at .msg files. I am also occasionally asked to dissect .msg files to ascertain their origin. Not only does this viewer allow me to view the .msg files, but it also allows me to view headers and plaintext views (on Mac only)! Also, it works across all of my Apple devices (Mac, iPhone, iPad)! Also, unlike many of the other apps on the app store, this is app is clear with its (reasonable) one-time price upfront. No wacky in-app purchases or subscriptions to deal with. The following minor complaints keep me from rating this 5 stars: 1. Inline images don't always load correctly, and you may need to dig into the attachments to view the image. 2. Viewing message headers is not available on iOS.

5. 5/5Just What I Needed

   A lot of my co-workers use Windows based PCs and when sharing emails through out systems, I end up with a ton of .msg files that I can't open, and it drives me crazy because I have to ask them to change it to a PDF, resend it to me, blah, blah, blah. Now I can skip that and get straight to the point. Best business cost I've incurred in a long time.
