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.

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.
