User testimonials
Free MBOX Viewer earns 62 reviews from buyers.
Collected across 62 reviews from portals and emails. Two reviews below are unedited.
I had over 300 MBOX files that I needed to access. Since I don’t use any MBOX compatible email client, the task seemed impossible to accomplish. Then, a friend of mine recommended this Corbett MBOX Viewer Software to me. I used this software to access and view my MBOX files and it provided me with a smooth and hassle free experience. This software is highly reliable. I even exported my MBOX files to my current email client for further use.
Viewing MBOX files without a compatible email client is not an easy task. But thanks to Corbett Free MBOX File Viewer Tool for making this extremely easy. The Message Header preview mode of this tool is incredible. It displayed the entire detailed routing information of the selected email message. Overall, this free Windows MBOX Reader is a great software for everyone.
