MiTeC Mail Viewer

MiTeC Mail Viewer is a lightweight and portable software utility designed for viewing standalone files which contain Microsoft Outlook Express 4,5 and 6 message database (.idx, .mbx, .dbx), Windows Vista Mail and Windows Live Mail message databases, along with EML files.
This type of tool may come in handy to all those who don't want to go through the trouble of installing email clients just to view some messages.

No installation necessary

Since there is no setup pack involved, you can save the program files anywhere on the disk and just click the executable to launch MiTeC Mail Viewer. It is also possible to copy the app to a USB flash disk to directly run it on any computer with minimum effort and no previous installers.
An important aspect worth taking into account is that it does not add new entries to the Windows registry or Start menu, thus leaving the disk clean after removal.

Simple and straightforward interface

The GUI is user-friendly and asks you to point out an Outlook Express or Mozilla Thunderbird message database, folder containing EMLs, or a single EML file at startup.
You can view the message content, as well as filter files by sender, receiver, subject and other aspects. Multiple languages are supported for the interface, so you can choose a preferred one.

Evaluation and conclusion

We have not come across any stability issues in our tests, since MiTeC Mail Viewer did not freeze, crash or display error messages. It has minimal impact on computer performance, so it doesn't hog CPU and memory. To sum it up, MiTeC Mail Viewer is a pretty good application for examining the content of emails, although it does feature an extensive list of options.
