This makes Mail Viewer interesting for users who want to export selected mails from a large Windows Live Mail or Microsoft Outlook email database. Selected messages can be saved to the eml format. Mail Viewer can display all email messages in detailed view including attachments with the option to save those and html preview & printing options. That's not really practicable as it would probably be easier to import those mails directly into a portable email client. The only possible way to display the emails from another user is to export those mails into the eml format so that they can be opened with the mail viewer application.

The only other option is to open eml files which works by pasting a path pointing to the file into the application.

It should be noted that the program is only able to open mail databases from the logged in user. The software program will display a wizard aiding you in locating and opening a mail database on the system. Add to that support for the generic eml mail format and you got a viewer that can view pretty much any mail format that has been used by Microsoft in its mail programs.
