When it comes to opening .eml email files, MessageViewer Lite is hard to beat. This inexpensive viewer accurately renders and prints individual .eml and .msg formatted email messages created by Outlook, Windows Live Mail, Thunderbird, Lotus and other email clients.

MessageViewer Lite has a limited set of features and is by design very easy to use. This has made it a popular tool for system administrators to deploy to their users.  After installation on a Windows device, any .eml or Outlook .msg file can be opened by clicking on it. The message will open up on your screen. Now you can print the email, or extract file attachments and save them to your hard drive.

File attachments can be dragged from the email and dropped on to the desktop.  Double clicking on a file attachment, such as a pdf file, will cause it to open in the appropriate software program on your computer.
