63 Best OST to PST Converter (2024) [FREE DOWNLOAD]

1. Introduction

1.1 Importance of OST to PST Converter

The OST (Offline Storage Table) and PST (Personal Storage Table) are two different types of data storage files utilized by Microsoft Outlook. PST files are utilized to store the personal information of users such as emails, contacts, calendar entries, tasks, and more. While the OST files contain similar data, but they are offline caches that need to be synchronized with the Exchange server or other systems, such as Gmail.com, Outlook.com, and Yahoo.com, etc. if you are working in IMAP mode.

Outlook can open PST files directly, but cannot open OST files directly if it loses the connection with the Exchange server or other systems. So there are many cases when one needs to convert OST files into PST format. For example, if the Exchange server crashes or experiences maintenance issues, the OST files become inaccessible as they cannot synchronize. It is in such instances that OST to PST converter tools become crucial. They allow you to access the data inside OST files easily.
