Six practical ways to open Outlook PST archives on macOS, with honest tradeoffs on search, export formats, privacy, compatibility, and price.
Last updated: September 6, 2026
PST Archive: Viewer & Exporter is the best overall option for Mac users who want free unrestricted browsing, local processing, selective export, and broad output coverage including EML, MBOX, CSV, PDF, VCF, ICS, TXT, RTF, and JSON. Its proposed Pro price is a one-time $19.99. Enolsoft PST Viewer is better when global search across folders and direct attachment preview matter more, but full access uses a subscription. Legacy Outlook for Mac remains useful only when the goal is to stay inside Outlook, and its support ends in October 2026.
| Rank | Product | Best For | Key Outputs | Price |
|---|---|---|---|---|
| 1 | PST Archive | Best overall local workflow | Archive, EML, MBOX, CSV, PDF, VCF, ICS, TXT, RTF, JSON | Free viewer and sample; proposed $19.99 one-time Pro |
| 2 | Enolsoft PST Viewer | Global search and attachment preview | EML, VCF, ICS, PDF | Free limit; $5.99/month or $19.99/year |
| 3 | PST Viewer & Converter | Current cross-device App Store option | MBOX and supported conversion formats | Free download; verify current in-app terms |
| 4 | PST Converter Pro - AppEd | Established one-time migration utility | MBOX, EML, VCF, ICS, Apple Mail Archive | $19.99 one-time |
| 5 | MacUncle PST Viewer | Older macOS versions and broad Pro formats | MBOX, EML, CSV, PDF, VCF, ICS and more | Free viewer; $29 Pro |
| 6 | Legacy Outlook for Mac | Importing into an existing Outlook profile | Imports PST into Outlook | Eligible Microsoft 365 or Office license |
PST Archive opens Outlook PST files in a native three-column Mac interface. Browsing is free, including items outside the export sample. You can search the current folder by title, sender, or recipient, select folders, and export mail plus other ordinary Outlook items into portable local files.
Enolsoft is a mature PST viewer with global search across folders or multiple PST files, attachment preview, printing, and export to EML, VCF, ICS, and PDF. Its free tier shows the first 10 items in each directory and exports up to 10 items.
This newer App Store product supports viewing, search, attachments, contacts, calendars, notes, tasks, and MBOX conversion across Apple platforms. It is useful if cross-device availability matters, but its public description is less specific about export coverage, free limits, and paid terms.
PST Converter Pro focuses on migration rather than a modern archive-review experience. It exports mail to MBOX, EML, and Apple Mail Archive, contacts to VCF, and calendar items to ICS. It remains attractive for older Macs and established Apple Mail migration workflows.
MacUncle offers free PST viewing and a $29 Pro tier with a large format list. Its official page highlights folder hierarchy, read-only access, header inspection, multiple-file support, and compatibility with older macOS releases.
Microsoft documents PST import into legacy Outlook for Mac. This is the right route when you already use Outlook and want the archive inside its local mailbox. It is a poor fit for portable exports, and Microsoft says support for legacy Outlook for Mac ends in October 2026.
| Goal | Recommended Format | Why |
|---|---|---|
| Move folders into Apple Mail or Thunderbird | MBOX | Keeps messages grouped into mailbox files |
| Save individual portable messages | EML | One standard MIME message per file |
| Review or print records | Human-readable fixed documents | |
| Analyze subjects, senders, dates, and fields | CSV | Opens in Excel, Numbers, and data tools |
| Move contacts | VCF | Standard vCard format for compatible contact apps |
| Move calendar events | ICS | Standard calendar interchange format |
Yes. A dedicated PST viewer can read supported Outlook PST files directly on macOS without Microsoft Outlook. Viewer, search, export, and compatibility features vary by product.
PST Archive is the strongest overall choice here for free unrestricted browsing, local processing, broad portable formats, transparent reports, and a one-time Pro option. Enolsoft is stronger for global search and attachment preview.
No. Convert selected PST mail folders to MBOX first, then use Apple Mail's File > Import Mailboxes command. Test the result before retiring the original archive.
Use MBOX for mailbox migration, EML for individual messages, PDF for readable records, CSV for analysis, VCF for contacts, and ICS for calendar data.
An online converter must usually receive the PST to process it. Because PST files can contain years of private email and attachments, local processing is the safer default.
No. Keep the original PST, read the conversion report, inspect warnings, and test representative output in the application that will receive it.
Browse for free, choose the folders you need, and export without uploading your mailbox.
