A single tool now lets Mac users open, preview, and convert PST files — no Outlook installation required.

MacSonik today announced the release of PST Viewer Pro, a utility built to solve a problem that has long frustrated Mac users: accessing Outlook PST files on a platform where Outlook for Mac often can't open them at all. With this release, individuals and organizations can view, search, and convert PST data directly, without ever installing Outlook.

Solving a Real Mac Problem

PST files are a Windows-native format, and Mac users have historically had few good options for opening them — especially orphaned files with no working Outlook profile behind them. PST Viewer Pro addresses this directly, letting users preview PST content, including attachments, in a clean and interactive interface built specifically for macOS.

The tool is designed for a range of scenarios: recovering data from old or orphaned PST files, working through large mailbox archives, opening PST files exported from any version of Outlook going back to 2003, or simply needing quick access to mail data on a machine where Outlook was never installed.

What It Does

At its core, PST Viewer Pro is a viewer and converter. Users can browse a PST file's original folder structure, inspect emails and attachments, and export data into a wide range of formats — including PDF, MSG, EML, EMLX, CSV, MBOX, and HTML.

The software also includes several features aimed at teams handling larger volumes of data:

Selective conversion using a date-range filter, so only the relevant window of mail gets processed
Duplicate removal across batches of PST files, matched on To, From, Subject, Body, and BCC fields
File splitting for breaking large output PST files into smaller, more manageable pieces
Custom naming and output locations for converted files, making results easier to organize and locate

The software runs on Apple Silicon (M1 through M5) and supports macOS versions from High Sierra through Sonoma and beyond, with a recommended 8GB of RAM.

Try Before You Buy

PST Viewer Pro is available as a free trial that converts up to 50 emails per folder, with unlimited scanning and previewing in the trial version. The full version unlocks unrestricted conversion, along with the same complete feature set — attachment scanning, duplicate elimination, selective data conversion, file splitting, and custom output naming.

Licensing is available across three tiers: a Home License for individual, non-commercial use; an Admin & Tech License for larger organizations and institutions; and an Enterprise License built for AMC service providers supporting external clients.

Availability

MacSonik PST Viewer Pro (version 26.06) is available now for macOS and Windows. More information, along with the free trial download, is available directly from MacSonik.
