BitRecover OST to PST Converter is a tool designed to convert your Offline Storage Table (OST) files into a Personal Storage Table (PST) format. This is particularly useful for situations where your OST file is inaccessible, corrupted, or you need to migrate your emails from a disconnected Exchange server.

The software is a standalone application, meaning you don't need to have Microsoft Outlook or an Exchange server connection to use it. It can handle encrypted and password-protected OST files and convert them while maintaining the original folder structure, email properties, and attachments. It also has features for batch conversion of multiple OST files and even splitting large PST files to avoid corruption issues.
