OST files allow Outlook users to work in offline mode when the connection between Outlook and MS Exchange Server is disrupted. Using OST files, users can access their user accounts present in the server database, even if the server is down. This is possible because, OST files contain the exact replicas of Exchange Server user mailbox accounts from which users can access their emails and other items. When connection is re-established between MS Outlook and MS Exchange Server, changes made in the user mailbox during offline work gets synchronized with the server database account. However, when connection with Exchange server becomes permanently severed, OST to PST conversion is required. In the absence of a dedicated connection, user account authentication and data synchronization fails. Hence, changes made in the OST files and in turn in user mailboxes become inaccessible. OST to PST converter free tools enable users to view their mailboxes complete with the offline work, even when Exchange Server is not available. These tools are primarily used to open and access the contents of orphaned or corrupt OST files. Common factors which make OST files orphan are Exchange server crash, permanently snapped connection, hardware failure at the server??™s end, Exchange database corruption and user account deletion in server database. OST to PST converter free tools like RecoveryFix for OST, however open the orphaned OST files and extract all their data to make user accounts re-accessible. Since OST files cannot be accessed using MS Outlook, these tools convert OST to PST format. Upon conversion, all the emails, email attachments, personal folders and items like contacts, calendar, address book, etc gets saved in a PST file. OST to PST conversion maintains data integrity without changing the metadata, format, properties and data structure of OST files.
