Univik OST to PST Migration is a desktop utility designed to transfer Outlook offline storage content into PST format for better accessibility and portability. Files stored in offline mode are often tied to a specific profile, which can make reuse or access difficult in different environments. This software provides a structured way to move such content into a more flexible format.

The application preserves message content, attachments, timestamps, and folder hierarchy during the process. It ensures that the resulting output reflects the original structure accurately, making it suitable for continued use within Outlook.

What Does the Software Do?

The tool allows users to load OST files and generate PST output that can be opened in Microsoft Outlook. It helps move stored information into a format that supports easier access, transfer and long-term use.

The source file remains unchanged during the operation.
