This is the software I've wanted for so long. Most of Google's suggestions aren't great when it comes to viewing all the details in the file. But MBOX Viewer is different. The simple but unique interface is very pleasant.

Now I can view all the *.mbox files easily. Get a lot of MBOX files, consisting of confidential data which makes it difficult to upload them on any online services. But now with MBOX Email Viewer, viewing email messages to getting all the information about the MBOX files has become very simple.

The tool works the same way as it professes. I used the reader tool to access Thunderbird MBOX files. I must say the MBOX Viewer does work brilliantly for a freeware tool. I was able to view multiple MBOX files at once.
