If you’re looking for a reliable way to access or recover data from an OST file, an OST to PST Converter is the perfect solution. OST (Offline Storage Table) files are created by Microsoft Outlook to store mailbox data for offline use. However, they can’t be directly imported into Outlook without converting them to PST format.
Why Convert OST to PST?
There are several situations where converting OST to PST becomes essential:
- Migrating to a new Outlook profile or computer
- Recovering mailbox data from an inaccessible or orphaned OST file
- Extracting data from a damaged Exchange account
- Creating a backup of offline Outlook data Since Outlook doesn’t provide a built-in option to import OST files directly, you need a third-party tool to convert them to PST format.
