PSTViewer Lite

PSTViewer Lite is a helpful application that lets you open PST files and see their content, without having to install Outlook.
The utility provides all the necessary tools viewing other mail formats like, MSG, EML, MHT winmail.dat and more. Converting to other file formats is also a useful feature that lets you store or share your emails under different formats. The PST files can be exported as PDF, MHT, HTML, BMP, GIF, TIF, BMP, PNG and TXT.
If you need to extract specific parts from your e-mails, keep in mind that attachments can be easily extracted from corrupted or unimportant mails, as well as password protected items.
As mentioned above, the Outlook client is not required to view archived messages, but with PSTViewer, you can still reply and forward emails, which is a great time and resource-saving feature.
The UI is split in two main parts, the “Explorer Tree” and the segmented preview window. The explorer tree lists all detected files stored on your PC, while the preview panel acts as an interface for the opened messages and their possible attachments.
All in all, PSTViewer is a handy email tool that provides full access to messages even if the client is not installed, and also lets you convert them to multiple formats as well as giving you the means to extract attachments from them.
