If you have a PST backup and just want to see what’s inside, this tool can help. The
MSOutlookHelp PST Viewer Tool allows users to
view PST files without Outlook and preview full email details like sender, subject, date, and attachments. It supports opening multiple PST files at the same time, which is useful when dealing with several backups. The software handles large PST files without size restrictions, so even heavy archives load without errors or delays.
