MiTeC Mail Viewer is a small tool to view the content of email database files without the need to install any mail client. The program supports databases of applications such as Microsoft Outlook Express 4,5 and 6 (in ISX, MBX and DBX format), Windows Vista Mail/Windows Live Mail and Mozilla Thunderbird. Stand-alone EML files are also supported.

The program allows you to preview the e-mail database file, including the detailed view with attachments. In addition, each correspondence can be printed or saved as an EML file. The advantage of the tool are extensive functions of searching and filtering mail.

Another important feature of MiTeC Mail Viewer is the ability to open multiple databases simultaneously, each of which is available from a separate tab. The application is available in several language versions, including Polish. It does not require installation and can be run from a flash drive.
