One of the most efficient ways to export OST to PST is by using the EmailProHelp OST to PST Conversion Tool. With its intuitive design, even non-technical users can operate it easily. The software allows OST file conversion into multiple formats, including EML, PDF, MSG, DOC, MBOX, CSV, TXT, and more. It also offers a PST split feature to manage oversized files and large OST data effectively. In addition, the Date Range Filter enables you to select and convert specific OST emails within a defined time frame, making the process more precise and convenient.
