How to open PST file without Outlook?

Want to check what’s inside a PST archive but can’t or don’t want to install Outlook just for that? This blog shows a straightforward way to open PST file without Outlook using a standalone viewer. The MSOutlookHelp PST Viewer displays full email details sender, date, subject, and attachments right inside the tool, so you can read messages without exporting anything. It also lets you open multiple PST files in one session, which helps if you’re reviewing more than one archive. Plus, it keeps your folder structure intact so you’ll recognize everything quickly.
