Need to read old Outlook archives but don't want to install Outlook? The MSOutlookHelp PST Viewer lets you open and browse PST files on its own. You can access emails, contacts, calendars, tasks and even notes without Outlook. It supports both ANSI and Unicode PST formats, so it works for old and recent archives alike. The tool handles large or multiple PST files at once, which makes it easy when you have many archives. Plus, the folder structure stays exactly as in the original file, so everything stays organised.
