Unlimited OST Files Recovery and Export
When managing multiple mailboxes at once, exporting several OST files to PST quickly becomes a practical requirement. This is common during large-scale mailbox recovery, data migration projects, or when working with inactive or disconnected Outlook profiles. However, built-in Outlook export options offer limited support, particularly for large, corrupted, or orphaned OST files, making bulk exports slow and unreliable.
EdbMails OST to PST Converter is designed to handle large-scale OST exports with ease, allowing unlimited file conversion without size limits. It supports all Outlook versions including 2021, 2019, 2016, and earlier, and ensures complete recovery of emails, calendars, contacts, notes, tasks, and attachments while preserving folder structure, metadata, and overall data integrity for both individual and organizational needs.
In this step-by-step guide, you’ll learn how to select OST files, configure export options, and save the data in PST format. With EdbMails, you can recover and convert Outlook data effortlessly, even from damaged OST files without relying on PowerShell scripts or manual setups.
Top reasons for exporting multiple OST files to PST
- IT teams managing several inactive or ex-employee mailboxes often need to export many OST files at once rather than one at a time.
- Large-scale migration projects and Exchange server decommissioning require converting entire batches of OST files without size or count restrictions.
- Organizations enforcing data retention or compliance policies need a reliable way to back up multiple mailboxes to PST in a single workflow.
