OST Files Opener Software Utility

Key Features of OST Files Opener Software

• OST Opener is a file viewing utility designed to open Microsoft Outlook Offline Storage Table (.OST) files without an Exchange server connection.
• OST files are local caches of email data; if the Exchange account is deleted or the server is unavailable, these files become inaccessible to Outlook.
• This tool solves that problem by allowing users to read the contents of "orphaned" OST files independently.
• The software scans the OST file and displays the folder structure (Inbox, Sent, Calendar, Contacts) in a tree view.
• Users can read emails, view attachments, and access contact details.
• It essentially acts as a specialized viewer for locked email data.
• While the free version is primarily a viewer, it is critical for users trying to verify if an old backup file contains the data they are looking for before purchasing a full recovery or conversion tool.
• It is a lightweight forensic utility for email recovery.
