What is an OST file and Why Outlook is Normally Required

Before we convert OST to PST without Outlook for free let’s learn a few important things.

When Outlook establishes a connection with IMAP servers, Microsoft 365, or Exchange, it generates an Offline Storage Table (OST) file that maintains a local copy of the synchronized mailbox data, allowing users to have access to their email while working offline.

Some of the most common features of the OST include:

• Encryption and profile tied.
• OST files are associated with one specific Outlook account.
• OST Files are continuously synchronized with the mail server.

Due to the structure of the OST files, they cannot be opened without using Outlook. Instead, Outlook serves as the authentication mechanism for opening the OST file. When either of these becomes unavailable (Outlook or the original account) any attempts to export Outlook OST file to PST without Outlook will be denied at the authentication level even though the associated data remains in the file.

Is it Really Possible to Export OST files to PST without Outlook?

Microsoft does not currently support an official way to convert OST files to PST using Outlook.

Therefore, it should be noted that technically, the OST files can still hold all of your mailbox data, even when the original email account no longer exists.

As such, all of the attempts made by a person manually to export an OST file to a PST file without Outlook will fail. Examples of attempted methods have included renaming the OST file, importing via another email client, or utilizing the operating system’s settings (Windows) to convert OST file to PST. None of these methods provide a useful way to change OST to PST without Outlook because none of them are capable of decrypting or interpreting the structure of the OST files, resulting in an unreadable or irreparably corrupted output.
