PST files totally belong to MS Outlook. Outlook has 100% authority on it and no one apart from it has the right to access it. Except there are now some tools that can make this thing possible by decrypting its internal programming to access its contents and display them.
WebbyAcad PST Converter is such a tool that can preview users emails, attachments, calendars, contacts etc all in one place. This is done by browsing the PST files on the software. As the name of PST file is displayed, move forward to the next step and double-click on Inbox. All emails will begin to display. Double click on the email and the email will be displayed along with its attachments.
This tool is helpful when your Outlook doesn’t work for some reason. Users can also convert PST content to other formats like PDF, MBOX, EML, MSG, TGZ, HTML etc. It is freely available on its official website.
