Converting Outlook Email to Different Formats

With Pst Viewer Pro, you can export emails to useful file formats.

First, select the email messages you want to export from the mail list. Next, choose the export profile from the drop down list. This image shows a few of the different formats and operations you can select from. In addition to converting emails to different formats, you can also choose to bulk extract specific types of email file attachments, such as all videos, or all PDF files, spreadsheets, documents, etc.  After the emails and export operation have been selected, begin the processing by clicking the “Export” button.

Outlook Pst Viewer Pro will then convert or extract your emails, saving them to a folder that you specify.

Outlook Email to PDF Conversion

Pst Viewer Pro has unsurpassed Email-to-PDF export capabilities. Choose one of five different approaches while converting emails from PST to PDF. Method 1 is to convert emails to PDF and extract file attachments to your hard drive. Method 2 is to convert emails to PDF AND also convert many file attachments types into the PDF images. Method 3 is to convert email to PDF with file attachments embedded as a separate file. Embedded files may be extracted from the PDF later. This preserves the context of the email and the attachments, while making sure the attachments can be utilized later. Method 4 is to individually export emails to an existing PDF file. This is useful if you are not able to export all of the emails in a single operation. When you find an email you want to save, you can copy it to an existing pdf file, storing multiple emails in a single PDF. Method 5 is to export multiple emails to a single .pdf file.

Because Pst Viewer Pro can work with OST, MHT, MSG, and EML files in addition to Outlook PST files, these methods apply to these other supported email formats as well.
