Yes, you can
read PST files on a Mac without using Outlook, but you’ll need a third-party solution because macOS does not natively open PST files. PST files are Outlook data archives that store emails, contacts, calendars, and more, so a compatible viewer or converter is required.
One option is a dedicated
MSOutlookHelp PST viewer tool that can open the file directly and let you browse its contents. These tools often work independently of Outlook and may support exporting data into formats like PDF or EML for easier access on Mac. Another approach is converting the PST file into a Mac-friendly format and then opening it in Apple Mail or another email client.
While some tools are free, advanced features like recovery, bulk viewing, or conversion usually require paid versions. Always ensure the software is from a trusted source before installing it.
