The simplest way to view PST files without Outlook is to use a dedicated PST Viewer. MacSonik PST Viewer allows you to open and preview PST files directly without installing Microsoft Outlook. It can display emails, attachments, contacts, calendars, and folder structures while maintaining the original mailbox hierarchy.
To view a PST file, install and launch MacSonik PST Viewer, add the required PST file, and browse its folders and mailbox items. You can preview individual emails and attachments without importing the complete PST into Outlook.
It also supports healthy, corrupted, orphaned, empty, oversized, and password-protected PST files, making it useful for accessing Outlook archives in different situations. If required, you can export selected mailbox data to formats such as PDF, EML, MSG, MBOX, CSV, or PST.
For users who simply need to access or inspect PST data without Outlook, a dedicated viewer provides a straightforward alternative.
