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.

Open MSG and EML files without Microsoft Outlook

Files with the Msg and Eml extension are self-contained email message files. They are usually created by email client software like Microsoft Outlook when someone wants to forward a complete copy of an email message to another person. Each msg or eml file contains
a complete email message, including internet header information such as the To/From/Sent data, and
file attachments.  Sometimes they
are created for email archiving or during a legal discovery process.  

While Microsoft Outlook can create .msg files and open them individually, it
does not provide a process for importing msg or eml files directly back into
the Outlook pst database program.  PstViewer Pro is a Windows software application that can help you manage a folder
with dozens or thousands of these files, even if you do not have Microsoft

Pst Viewer Pro lets you display Outlook .msg files formatted as a rich text, html or text.  You can search a
directory of msg or eml files, discover the files that are important to you, and
then view them, access file attachments, print, or convert them to pdf and
other formats, including text, mht, html, and image files such as .gif, .tif,
.png, .bmp.

With Pst Viewer Pro, you can reply to emails through the default email
client app on your computer. Pst Viewer Pro supports Reply, Reply All, or
Forward email with file attachments.

Retrieving file attachments from Msg or Eml Files
Often the most important part of an email are the files that are
attached to it. Pst Viewer Pro gives quick access to file attachments. You can
simply click on the attachments to open them in their native application. You
can right click on file attachments and save them to a folder on your computer
hard drive, or you can drag and drop file attachments from Pst Viewer Pro to
your desktop.

What if you have thousands of msg or eml files and you want to extract all
file attachments?  Pst Viewer Pro makes
this a very easy task.  First, select all
of your emails in your maillist (ctrol-A will select all emails). Next choose “Only
Attachments” from the email export drop down list, then click the “Export”
button. Pst Viewer Pro will examine each .msg or .eml file and if it finds an
attachment, it will make a copy of the attachment and save it  to a folder location that you specify.

Export MSG or EML files to PDF
Pst Viewer Pro can export msg and eml files to PDF files. Whether you have one email file or thousands of them, Pst Viewer Pro can convert them into PDF files in a single bulk operation. Special features are included for handling email file attachments, which may optionally be extracted to a folder on the hard disk, converted into the PDF image, or stored as separate files within the PDF.

A Single Email Viewer App for Accessing Multiple Email Formats

Email content stored in different formats can be inconvenient to search and manage.With  PST Viewer Pro, you can open up to seven common email file types with this single Windows software application.

Pst Viewer Pro will open Outlook PST and OST files. These files contain multiple email messages, including their file attachments. They are typically larger files (2 GB is very common). Until recently only Microsoft Office Outlook could open these types of files, but publication by Microsoft of the PST file specification has allowed software developers to access these files.

Pst Viewer Pro will also open Outlook MSG files. These are individual email messages that have been saved outside of an Outlook PST or OST file.  A .MSG file contains a single email message. They are often created  when an Outlook user forwards an email or saves a message to their hard drive.

Occassionally, email messages created by Outlook will arrive in a non-Outlook email client as a Winmail.dat file.  These files are often caused by the fact that Outlook formatted .msg files do not conform to the RFC-822 or RFC-2822 standard.  They are used to preserve Rich Text formatting of a Microsoft Outlook generated email. During transport of the message over the internet,
the content of the message may be changed, preventing email
client from reading the formatting instructions. Pst Viewer Pro can also open winmail.dat files, even when your email client cannot.

Pst Viewer can also open .EML files, which are RFC-822 compliant email transport documents. They files are created by email clients such as Mozilla Thunderbird or Windows Live Mail.  EML files are similar to MHT or MHTML “mime html” files, which are self-contained HTML files. MHT or MHTML files contain all of the formatting information, images, text, etc., within the file.  Web pages are often archived in this format because sharing a website as a single file instead of many individual files is very convenient. MHT and MHTML files can also be viewed by Pst Viewer Pro.

Pst Viewer Pro supported file types:

MSG (Outlook)
OST (Outlook)
PST (Outlook)
EML (RFC-822)

In addition to its viewing capabilities, Pst Viewer Pro can be used to export messages to PDF and other image formats such as BMP, TIF, GIF, PNG and JPG.  It can also save emails a CSV spreadsheet files, or text files.
