Outlook email messages  can exist in range of email formats, including .msg files, or .ost,  .pst files.  Even those formats have variations.

.MSG files are individual emails, and they come in the older Ansi and Unicode formats, and then in text, rich text and html formatting.  PST files contain many email messages. A .pst file created by older Outlook versions (pre-2003) also may also exist in ANSI format, while later files are in Unicode format.

With email stored in so many different formats today, archiving and accessing these files can present some challenges. That’s where an email viewer like Pst Viewer Pro is a handy addition to your Windows software toolbox.

Pst Viewer Pro is a single software app that can open all forms of .pst, .ost and .msg files. It can also open .eml files which are produced by email clients such as Thunderbird, Windows Mail or Outlook Express, as well as .mht/.mhtml, and winmail.dat files.

Email Formats Supported

Outlook .pst
Outlook .ost,
Outlook .msg
.eml
winmail.dat
.Mbox

Using the Mail List

Individual emails are displayed in Pst Viewer Pro’s mail list window. You can sort the list quickly by clicking on the column headers.

Mail List Window

A viewing pane below the mail list lets you preview the selected message.  To open the message in a full and separate viewing window, just double click on the message in the list.

With PST Viewer Pro, you can easily access file attachments in the email.  Double click on them to open them in their native application, or save them directly to your desktop, either by dragging and dropping the file outside of Pst Viewer Pro, or by using a right-click operation and selecting the destination folder for the files.

Searching For Email

Pst Viewer Pro supports detailed search operations to help you locate the messages you need. On the main tool bar, you can do a quick search just by typing in a keyword you would like to find.  Quick search goes across all fields and displays messages with that keyword.

Conversion of Email to PDF, Other Formats

Some times it is convenient to save a message as a pdf or image file. Pst Viewer Pro provides strong capabilities in this area.    Converting email is a simple matter of selecting the messages you want to export and then indicating the desired format from the main toolbar.

To select all emails in the mail list, type ctrol-A.  You can also choose emails individually, or using the shift key you can choose a range of emails.

The Pst Viewer Pro main menu allows you to select the export profile you require.  Several different methods of export-to-pdf operations are supported.

Select the PDF export profile.

How you choose to manage email file attachments are important. While any virtual PDF printer can allow you to print an image of the email to pdf,  few applications if any have Pst Viewer Pro’s ability to let you manage file attachments in such a variety of important ways.

You can export email to pdf with file attachments embedded as individual file within the pdf. You can extract the file attachments to a location on your computer, removing them from the pdf altogether.  Or, you can attempt to convert the attachments into the pdf image; in this case the email will first be imaged, and the attachments will follow.  If the attachment cannot be imaged (for example if it is a binary file) then it will embedded within the pdf as a separate file.

Pst Viewer Pro also supports the PDF/A (ISO 19005-1) standard for long term archiving of email messages. In this mode, fonts are embedded within the pdf so that the message can later be rendered accurately.

Also supported is the export of multiple emails into a single PDF file, and the appending of selected or individual email messages to an existing PDF file.

In addition to PDF, Pst Viewer Pro also can also convert your Outlook email to the following formats:

MBOX
DOCX

EML
CSV
