MessageViewer Lite is an easy to use email viewer for .eml, .msg and .mht files. Designed to be a very simple way for non-technical users to click on an email and have it open, MessageViewer Lite has found favor with busy system administrators.  If you just want to click on an .eml and .msg file and have it accurately rendered each time, then MessageViewer Lite is for you.

MessageViewer Lite provides access to email file attachments, supports printing, is switchable between viewing in html or text. MessageViewer Lite is well known for its ability to display even the most complex Outlook email messages, such as those with embedded OLE objects, smartart, and embedded images. Hundreds of non-standard formatting exceptions have been culled from the wild and incorporated directly into MessageViewer Lite, making it probably the most accurate email rendering tools ever.

On the outside, MessageViewer Lite retains its clean and simple look in version 4.5, but under the hood are several important enhancements in the software’s email parsing engine and enhanced stability, making this a maintenance release recommended for all customers.

A Look At MessageViewer Lite, The Simple .EML Viewer

Screen image of Message Viewer Lite menus.

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.

Easy to use .eml or .msg email file viewer, MessageViewer Lite.

MessageViewer Lite supports having multiple windows open, each showing a different email message.  Content can also be copied and pasted directly from the email window. MessageViewer Lite can be deployed to user desktops. It can also be used with hosted applications, such as a CRM app,  so that users will always have the ability to open email messages attached to client records.

MessageViewer Lite has just three menu items File, View and Help.

The File menu gives access to the Print function which will send the email to your printer.
Check File Associations will let you set MessageViewer Lite as your default Windows application for .eml or .msg files.

From the File Menu, you can also set file associations for MessageViewer Lite.  Set it as the default application for .msg or .eml files.

The View menu has just one option that toggles the viewer between html and text mode. If you set it to text mode, then MessageViewer Lite will always display.eml and .msg files as text files, rather than html files.

The Help menu contains several useful options.
