OST to Apple Mail is about getting the data, mainly emails, across two majorly different clients – Outlook in Windows and ‘Mail’ in MacOS. Not just that, the OST file is not a personal data file (like PST or MBOX) that you employ for data migration to some degree.

OST, short for offline storage table, is an internal file that allows Outlook to store data locally and still be in sync with the email serves, all the while, allowing you to work offline too. This is a great way to access email data in Outlook, but the problem is that OST file is pretty much useless outside the context.

Unlike PST, MBOX, EML, or similar data files that can be utilized for backup, archiving, import/export, at least within the same email clients, data in OST will become inaccessible after the “link” or “internal connection” with Outlook is broken for any reason.

It happens frequently:

  • If you delete the original email account and only keep OST files as your backup for data, you are out of luck. There is no way you can import it to Apple Mail or even Outlook for that matter.
  • Virus or malware can often disable the functionality of OST file and become isolated
  • Events like power failure, hard drive failure, etc. also negatively impact the file’s nature and its ability to access data in Outlook.

All of that creates a disheartening and exhausting situation for Outlook users who want to import the file to Apple Mail.

But believe it or not, there is a way you can get over this seemingly tedious task.

Convert OST to MBOX or Apple Mail native folder

The data in OST files is intact; it is just that the OST format is not applicable for importing data anywhere.

But that leaves you with one option: changing or convert the format itself.

With the help of third-party tools, you can convert the file to new files with different formats, depending on where you want to import your emails. For our case here, you can convert OST to either MBOX or to “Mail” native folder directly and then import them to the ‘Mail’ database on MacOS X.

This sounds simple enough except with a badly developed converter, you can end up with even worse results, like data loss and data integrity loss.

Not to mention, often, the generic OST converters are hard to operate due to their sloppy interfaces and rigid functionality. And given the complexity and crucial nature of emails in modern-world, it is suggested to avoid any programs or tools that do not guarantee data safety and do not offer simple interfaces.
