Kernel OST Viewer

Kernel OST Viewer is an easy-to-use program developed for displaying orphan OST files (Microsoft Outlook). It is accompanied by user-friendly options and a comfortable interface.

Setting up the program is done rapidly. Its GUI is represented by a well-structured window with a clean aspect, where you can point out an OST item for display using the file browser. Unfortunately, drag-and-drop is unsupported.

Alternatively, you can ask the program to search for all compatible files. By using a tree view it is possible to navigate directories within OST files, in order to locate messages in various categories.

These are listed in rows on the top half of the screen (along with the sender, subject, time and date, and lost/deleted status for each item), while the lower area is reserved for showing message content (including attachments). You can quickly switch to the calendar, contacts, task, and notes. There are no other notable options available here.

The program runs on a very low amount of CPU and RAM, so it does not affect the overall performance of the computer. No error dialogs were shown in our testing, and the tool did not hang or crash. We have not come across any issues.

To sum it up, Kernel OST Viewer offers a simple solution for viewing OST files without using Microsoft Outlook. Thanks to its intuitive layout, it can be handled even by users with no previous experience in such apps. Unfortunately, the software application has not been updated for a while.
