Convert OST Files to a PST File (Advanced Utility)
OST to PST conversion is the process of transforming Offline Storage Table (OST) files into Personal Storage Table (PST) format so that Outlook mailbox data can be accessed independently of the Exchange Server. OST files are created when Microsoft Outlook is connected to an Exchange, Office 365, or IMAP account and work as an offline replica of the mailbox. These files are encrypted and tightly linked to the original Outlook profile, which makes them inaccessible if the Exchange server crashes, the account is deleted, or synchronization fails.
When an Exchange Server becomes unavailable due to server downtime, corruption, profile deletion, or organizational changes, users often lose access to their OST files even though the data still exists locally. In such situations, OST to PST conversion becomes essential because PST files can be opened directly in any Outlook profile without server dependency. This conversion ensures business continuity and prevents permanent email data loss.
