Typical use
A long-running Mac PST viewer with global search, attachment preview, EML, VCF, ICS, and PDF features offered through a recurring subscription.
Great Apps advantage
PST Archive includes free unrestricted browsing, MBOX and CSV output, explicit machine-readable reports, and a one-time Pro unlock instead of a subscription.
Typical use
A one-time-purchase Mac converter focused on moving PST mail, contacts, and calendars into common migration formats.
Great Apps advantage
PST Archive combines free in-app browsing with selective export, PDF and CSV output, issue reporting, and broader mixed-item preservation.
Typical use
Microsoft's legacy Outlook can import PST data into its own local mailbox, but support is scheduled to end in October 2026 and the workflow requires an eligible Outlook or Microsoft 365 license.
Great Apps advantage
PST Archive reads the source directly, requires no Outlook installation, and exports portable files rather than importing everything into a live Outlook profile.
Typical use
Browser services may require mailbox archives to be uploaded before conversion and commonly impose file-size or processing limits.
Great Apps advantage
PST content stays on your Mac, with no archive upload, cloud conversion, account, or server-side mailbox processing.
Yes. PST Archive reads supported Outlook PST files directly on macOS, so Microsoft Outlook is not required for browsing, searching, or exporting the archive.
No. PST contents are viewed and converted locally on your Mac. The app does not upload messages, attachments, contacts, calendar items, or generated output to a conversion server.
The viewer supports ordinary mail, contacts, contact groups, calendar events, tasks, notes, journals, and other mapped items inside the PST folder hierarchy. Unsupported or uncertain records are reported rather than silently treated as complete.
Choose Archive, EML, MBOX, CSV, or PDF. Applicable non-mail records can also be saved as VCF, ICS, TXT, RTF, and JSON, with reports and supported attachments alongside the output.
Yes. Search the current folder by item title, sender, or recipient. The viewer does not claim body-wide or cross-folder full-text indexing.
Known PST passwords can be entered and validated locally for supported archives. The password stays in the open session and is not stored in reports, preferences, or Keychain. This is password validation, not password recovery.
No. PST Archive opens the source read-only and creates each export in a new output directory. Keep the original PST because portable exports are not a replacement PST or a universally lossless backup.
Scanning and read-only browsing are free. Sample exports include the first 10 ordinary items per type across the PST. A one-time PST Archive Pro purchase removes those sample limits.
No. PST Archive Pro is a one-time, non-consumable in-app purchase. The app displays Apple's current localized price before purchase.
PST Archive creates one mboxrd mailbox per selected mail folder. Apple Mail and other compatible clients can import MBOX files, but import behavior is controlled by the receiving application.
