Converting OST files to PST is essential when you need to move or back up Outlook data, especially if the original account is inaccessible. This conversion allows you to retain access to your emails, contacts, and other Outlook items across different devices and accounts. The process can not be done using Outlook's built-in tools, and specialized software is required, especially for handling large files, orphaned OSTs, or bulk conversions.

How It Works

The utility converts OST files into PST format, ensuring that all data—emails, attachments, contacts, calendar events, and more—are preserved. You can selectively choose what to convert, filter by date, and even split large files into manageable parts. The tool also allows you to merge multiple OSTs into one PST file, making it easier to manage your Outlook data.

Key Features

• Compatibility: Works with most of OST file types, Windows and Outlook versions.
• Data Integrity: Preserves folder structure, metadata, and formatting.
• No Limits: Handles large OST files and batch conversions efficiently.
• Offline Operation: Converts OST files without needing an Exchange Server connection.
• Selective Conversion: Choose specific items to convert, skip empty folders, and organize data by various criteria.
• Bulk and Scheduled Conversion: Supports command-line operations for automating conversions.

Why It’s Needed

• Accessibility: OST files are linked to the original Outlook account, limiting their use. Converting them to PST makes the data accessible across different accounts and devices.
• Backup: Convert OST to PST to create a backup that can be stored locally or in the cloud.
• Migration: Essential for moving data to a new Outlook account or when upgrading systems.
• Data Recovery: Retrieve data from orphaned or archived OSTs that are no longer linked to an active account.
