An OST (Offline Storage Table) file is created by Microsoft Exchange to allow offline access to mailbox data. However, when Exchange Server is unavailable, or the profile is disconnected, converting OST to PST becomes necessary for data access and migration.
The most efficient way to perform this task is by using a professional solution like the SysVita OST to PST Converter. This tool ensures safe conversion without data loss and supports emails, contacts, calendars, tasks, attachments, and folder structures.

The software supports corrupted, encrypted, and oversized OST files and allows direct export to Office 365, Exchange Server, and IMAP accounts.
