If you need to access PST emails, contacts, and calendars without Microsoft Outlook, the easiest option is to use a standalone PST viewer. A dedicated tool can read the PST file directly without requiring an Outlook installation or an active Outlook account.

MacSonik PST Viewer lets you open PST files on Windows and Mac and preview emails, attachments, contacts, calendars, tasks, drafts, and other mailbox items while maintaining the original folder hierarchy. It also supports healthy, orphaned, minimally corrupted, oversized, password-protected, and empty PST files.

You can simply add the PST file, browse its mailbox folders, and preview the required data. Advanced search filters can help locate emails by sender, recipient, subject, date range, or attachments.

If you need to save the data after reviewing it, MacSonik PST Viewer supports exporting mailbox content to formats such as PDF, EML, MSG, MBOX, CSV, PST, and Microsoft 365.

So, if your goal is to view PST emails, contacts, and calendars without Outlook, a standalone PST viewer like MacSonik provides a convenient way to access the archived mailbox directly.
