Yes. You can view emails, contacts, and calendars stored in a PST file without installing Microsoft Outlook by using a dedicated PST viewer.
MacSonik PST Viewer  lets you open PST files and preview mailbox data such as emails, attachments, contacts, calendars, tasks, and drafts without requiring an Outlook account or license. It also provides options to search mailbox items and inspect email details, folder structure, headers, and attachments.
For users who only need to access or examine PST data without Outlook, this can be a convenient alternative to setting up Outlook just to view an archive. You can learn more about the features and supported options on the MacSonik PST Viewer page.
