If you need to access emails, contacts, and calendars stored inside a PST file, you don’t necessarily need Microsoft Outlook. A standalone PST viewer can be useful when the original Outlook profile is unavailable or you simply want to inspect an archive without importing it.
One option is the MacSonik PST Viewer , which allows users to open PST files on Mac or Windows and preview different mailbox components. After adding the PST file, you can browse its folder structure and access emails, attachments, contacts, calendars, tasks, drafts, and other mailbox items. It also lets you inspect email details such as sender, recipient, subject, timestamps, headers, and attachments.
The tool supports healthy, orphaned, password-protected, oversized, and minimally corrupted PST files without requiring Outlook. You can also search mailbox data using filters such as sender, recipient, subject, date range, or attachments. After reviewing the required information, the data can be exported to formats such as PDF, CSV, EML, MSG, MBOX, PST, or Microsoft 365.
