Want to access a PST file on your Mac without installing Outlook? It's easier than you think. PST files store emails, contacts, and attachments from Microsoft Outlook on Windows, but macOS can't read them directly. The detailed guide on this blog: Open PST File On Mac With/Without Outlook - Expert Solutions walks you through several proven methods. One option is Mozilla Thunderbird with the ImportExportTools NG add-on, allowing you to import PST data and read messages offline. Another is using an IMAP-enabled email account: import the PST into Outlook on a Windows PC, sync it to Gmail (or another IMAP service), then open the synced account in Apple Mail on your Mac.

For the quickest and most reliable route, try the Cigati Outlook PST File Viewer. This professional tool instantly opens and previews emails, attachments, and entire folder structures--no Outlook installation or complicated setup required.

Quick Tips:

Back up the PST file before you start.

Split oversized PST files for smoother handling.

Make sure your Mac mail client supports your chosen method.

A dedicated PST viewer saves time and reduces the chance of data loss.
