Comparing PstViewer Pro And PstViewer Lite Outlook Email Viewers

One of the most frequently asked questions of the Pst Viewer support team at Encryptomatic LLC is, “What is the difference between the Lite and Pro PST viewers?”  This article will answer that question in detail.

PstViewer Pro began as a simple .msg file viewer in 2006.  Over the years, feature creep added many new and useful capabilities to the software. Some of these features required the addition of expensive 3rd party libraries and many hours of development.  Some of these capabilities are quite specific and enable customers to manage and convert email from Outlook .pst, .ost, .msg, and .eml files in complex ways.

Pst Viewer Lite was introduced in 2011. It was designed to fill a gap in the market for a high quality, low cost Outlook email viewing tool that is simple to use.  Priced at just $29.99 for a single license with quantity discounts available, Pst Viewer Lite has found a home in many organizations around the world.

By comparing the opening screens for Pst Viewer Pro and Lite, it appears at first glance that they are not very dissimilar. The navigation and main viewing panes are very similar between the two. Both share the same high quality email rendering engine (MVCOM) that has more than 200 non-standard email formatting exceptions coded into it.  Both can display emails formatted as html, text or rich text.

Neither has difficulty displaying embedded email graphics.  Each of them provides access to email file attachments.

Printing of individual messages, and saving email as individual .pdf files is supported by both. You can also use either product to add individual email messages to a single .pdf file.

Neither Pst Viewer Pro or Lite requires that Microsoft Office Outlook be present on your Windows computer or tablet. Both function completely independent of Outlook and do not have a MAPI dependency.

Both Pst Viewer Pro and Lite provide quick search and advanced search functions, allow users to locate important messages.

Support is offered for both products, and a year of free updates is included when you purchase either.

With so many similarities, what differences exist between these viewers, besides price?

The differences between PstViewer Pro and Lite
Probably the most importance difference is bulk processing of email messages.  While Pst Viewer Pro and Lite share many capabilities, Pro is suited to bulk export conversion and printing of email content, including mixed content ( i/e .msg, .eml files togther in a single mail list).

Most of the differences can be seen on the quick access toolbar of both products, shown here.

Pst Viewer Pro makes use of Export Profiles.  They are displayed in a drop down list on the main toolbar.  Any export profile may be edited, deleted, or new export profiles may be created. Profiles are instructions that cause Pst Viewer Pro to act in a certain way. For example, they can include instructions on how exported emails should be named, or where files should be copied, or whether a copy of email file attachments should be saved to your hard disk.

Export profiles and bulk processing of messages allow Pst Viewer Pro to accomplish a wide variety of specialized tasks for our customers, saving them time and making them more efficient.  It accomplishes tasks that heretofore has required several software packages or much more expensive software packages.

Is Pst Viewer Pro or Lite best for your needs?
If you just need quick access to .pst, .ost, .eml, .msg or winmail.dat email files, and bulk conversion to PDF and other formats is not part of your mission, then Pst Viewer Lite is a great choice for you.

For bulk processing of email and converting to PDF format, then Pst Viewer Pro is the better choice. At $69.99, it is a bargain compared when comparing capability against cost.

You can download a free trial of either Pst Viewer Pro or Lite. A 15 day free trial is offered for both. You can also install and run both Lite and Pro on the same computer at the same time.

Comparing Outlook PST Viewers.

Outlook .pst viewers come with different basic capabilities. Choosing the right viewer will help you manage your Outlook email content. 

The first question should be, why use an Outlook viewer at all?  Why not just use Microsoft Outlook? While Outlook is an excellent product and the choice of millions of people, its not everyone’s choice. Some people get along just fine with Windows Mail or Thunderbird email clients.  An Outlook viewer is also helpful if you have accumulated many pst files, and you don’t want to co-mingle your current email with the older files.
There are three tiers of email viewers available today: Free, Simple and Advanced.

Advanced Outlook Pst Viewers
The features found in an advanced Windows pst viewers may include capabilities that take you beyond Microsoft Outlook. Pst Viewer Pro is the viewer that we develop. It includes a customer driven feature set that includes advanced export capabilities which are particularly developed around conversion of email to pdf files. Pst Viewer Pro lets you bulk convert email in pst files to pdf with options for how to handle attached files. For example, you can extract the file attachments, embed them within the pdf as as separate file, or convert many popular document file types into the pdf image.  You can also save selected email messages to an existing pdf file.

Pst Viewer Pro also has an advanced search ability to help you find those important messages. specific searches can be performed based on specific fields. You can search emails that fall between specific dates.

An advanced viewer like Pst Viewer Pro may also provide the ability to manage email content in different formats. Besides pst files, it can also open Outlook .ost, .msg, .eml and even MIME HTML .mht or .mhtml files.  It also opens winmail.dat files.

Simple PST Viewers
Maybe you have a few pst files you need to open, but you don’t necessarily need to have bulk export capabilities.  You just need a good quality viewer that can search your pst files, display the emails accurately, let you open email file attachments, print, reply, and maybe export the occassional email to pdf

Pst Viewer Lite was created with simplicity in mind. Most the important functions for Pst Viewer Lite are located on the mail tool bar where they are quickly accessible. The main difference between Lite and Pro is that Lite will not bulk export pst to pdf and other formats. Emails can be individually exported.

To use Pst Viewer Lite, use the folder nav on the left side of the product screen to select the location of your pst files.

Click on the pst file to reveal the folder structure. Click on a folder to display it’s contents. To display all of the contents of the pst file at the same time, right click on the pst file and choose “Scan with subfolders.” Now when you click on a pst file folder, all emails in subfolders will also be displayed.  Turn this feature off, and only the emails in the selected folder are displayed.

At $29.99, Pst Viewer Lite packs a lot of features and quality into a very small price. No corners were cut on search functionality, as Pst Viewer Lite has the same advanced search options as Pro.

Free PST Viewers
There are several free Outlook viewers available, and finding them is not difficult. We have tested most if not all of them, and have found them lacking in several areas.

First, nothing is truly free on the internet, and any software developer who plans to stay in business must find a way to generate revenue.  Some of them earn money through advertising, while others turn to pay-per-install software. During the installation process of a free pst viewer, if you are not very careful you may find that you have installed unwanted software on your computer.  

Another way that some free .pst viewers make money is by trolling for damaged pst files, and then offering to install you an expensive software package when one is encountered.  We noted at least one “false positive,” where a free viewer said that a file was corrupt and suggested we buy their pst repair software, yet we were able to open that same pst file in Outlook and with a commercial viewer.  If a free .pst viewer suggests that you buy expensive software, a second opinion is definitely in order.

Be sure that any pst viewer software installer that you download is “code signed.”  This means that when Windows begins to run the installer package, it is can display the verified name of the software developer who created the software.  When you start a software installer that is unsigned, Windows will display a notice that says the developer is “unknown.”  Unsigned software code is dangerous, as it means that the software installer may have been tampered with.  Reputable software developers will purchase a code signing certificate. By signing their code they are protecting you as well as their reputation. Unfortunately the installers for all free pst viewers we tested in September, 2012, were unsigned.

There are many options when choosing a pst viewer. Choose one with a feature set that meets your specific needs, and is built by a reputable software developer.

If a free PST Viewer does not meet your needs, try Pst Viewer Lite. It’s both affordable and very effective at opening and rendering email from .pst files.
