OST files, short for Offline Storage Folders, are a Microsoft-provided feature designed for storing user information and email data in offline mode, commonly known as Cached Exchange Mode. These OST files contain a synchronized copy of mailbox data from the Exchange Server. They enable users to access their data even when not connected to the Exchange server. OST files offer the advantage of seamless offline work, allowing you to save and utilize your data without an active connection to the Exchange server.
OST files may experience corruption and become inaccessible due to a range of software and hardware-related issues. In typical scenarios where the Exchange Server is operational, recreating an OST file is a straightforward process: simply delete the existing OST file, and the Exchange Server will automatically generate a new OST file containing all the original data. Alternatively, you can attempt to repair the Outlook profile or run Outlook in Safe Mode to regain access to the OST file’s data.
However, there are instances where you are left with only the corrupted OST file and no immediate server connection. In such cases, it becomes necessary to undertake OST file repair to restore access to its contents.
There are 3 ways to view corrupted OST files; we are enlisting them below:
Consider using the automated tool Kernel for OST to PST Converter for repairing and recovering corrupted OST files.
Previously, Outlook users had access to a tool called Scanost.exe in earlier versions of the software, which allowed them to open and view severely corrupted and damaged OST files. This utility was capable of repairing these compromised OST files and was often referred to as the OST Integrity Check Tool because it initially assessed the file’s integrity. Scanost is located at at Drive:\Program Files\Microsoft Office\Office version. It’s important to note that this tool did not alter the data within the OST file during the repair process.
Scanpst.exe is a reliable tool that can handle both OST and PST files effectively. This inbuilt utility, provided by Microsoft, is designed for opening, viewing, and repairing severely corrupted and damaged OST files, as well as PST files. Often referred to as the Outlook Inbox Repair Tool, scanpst is located in the MS Office installation folder and is a valuable resource for managing MS Outlook data files.
The Kernel OST viewer is a free tool designed for opening and viewing both corrupted and damaged OST files. This user-friendly utility provides a straightforward experience with its intuitive graphical user interface. It allows you to effortlessly open and view damaged OST files without requiring the original profile. All you need to do is select the damaged file, and the tool opens it instantly for your convenience.
Due to the above advantages, there might be many who would think of using the Kernel OST Viewer. The tool can be used following these simple steps:
Note: The other three reports can be generated similarly.
