PST Converter
Opens Windows Outlook archives on a Mac that has never had Outlook on it.
Seventeen tools that open PST, OLM, MBOX and EML files on macOS without Outlook. Every one reads the source read only and runs on your own Mac.
Six tools that cover the files that turn up most often. Across the full range prices run from $25 to $79, and every tool has a trial you can run first.
Opens Windows Outlook archives on a Mac that has never had Outlook on it.
Apple Mail and Thunderbird exports, turned into whatever the other side asked for.
Frees Mac Outlook data out of a format almost nothing else will read.
One local archive of a webmail account, made before someone closes it.
Take a copy of tenant mailboxes and keep it where Microsoft does not control it.
For when Mac Outlook will not start and the profile looks beyond saving.
Four of them move your data somewhere you can use it and leave the original alone. The fifth makes sure it is gone for good, which takes more than emptying the Trash on an SSD.
Turn one mail format into another. Five converters covering the files people get stuck with most.
Pull a mailbox down off the cloud before an account closes or a person leaves.
Get at what sits inside the file. Attachments and images out in bulk, not one by one.
For the day a file will not open. Repair it, or pull out whatever is still readable.
The other direction. Wipe data so no recovery tool can bring it back.
Every converter, backup tool and extractor works the same way. Read a mail file or sign into a mailbox, write it somewhere usable.
Metadata is carried across on every route. Sender, recipients, timestamps, message headers, read status, folder hierarchy and attachments all survive the trip. Tested against macOS 12 Monterey through macOS 15 Sequoia on both Apple Silicon and Intel.
A mailbox file is often the only copy left. These tools are built around that, not around speed benchmarks.
PST, OLM and MSG files open directly on macOS. You do not need Outlook installed, licensed or even present on the machine.
Nothing is written back. Output lands in a separate file you choose, while the file you pointed at keeps its original bytes and timestamps.
The trial reads your actual file and shows you what is inside. You find out whether it works on your data before money changes hands.
One universal build covers every Mac from macOS 12 onward, Apple Silicon or Intel. Signed with an Apple Developer ID and notarized, so Gatekeeper lets it through.
Every conversion, backup and repair runs on your own machine. Your mail is not uploaded to a server, not queued as a cloud job and not held anywhere we could read it.
That covers the file as well as the network. Take a checksum before and after and the same digest comes back, because nothing is ever written to the source.
“We had 60 staff mailboxes to pull down before a domain move. I set the date range, pointed it at a folder and left it running overnight. Nothing was missing in the morning.”
“A client sent over an archive Mac Outlook would not touch. The preview showed me what was recoverable before I paid anything, which is why I bought it.”
“We work entirely on Apple hardware and the other side sends Windows Outlook archives every single time. This opens them without an Outlook licence sitting on a machine somewhere.”
No. The converters read the file directly, so Outlook does not need to be installed or licensed on the Mac.
No. It is opened read only and the output goes somewhere else entirely. Run shasum on the source before and after if you want to prove it.
Every tool runs a full preview so you can see your data before you decide. The licence is what unlocks saving and exporting.
Yes. Every tool ships as a universal binary that runs natively on M-series and Intel Macs.
No. Everything runs on your Mac. Backup tools connect only to your own mail server and your password stays on the device.
The tools run on macOS 12 and later, on both Apple Silicon and Intel.
