  • It is convenient, and most importantly has a clear interface. This allows you to understand very quickly what exactly needs to be done to convert or view the contents of the file.
  • You can view not only letters but also messages, notes, information about appointments, and so on.
  • All data can be sorted by type: to whom the message was sent, where, it was sent, and the like. Also, files can be sorted by date and other criteria.
  • The tool is even able to view corrupted files, which can be extremely useful for Outlook users.
  • OST Viewer interacts with files created in the Outlook 97-2003 interface.

We remind you once again that the demo version allows you to export and save only the first 5 files. However, viewing is available for all data.

Features of Using the Tool

Many users wonder how they can open a file that is too large, the size of which is 4GB or more. This requires a 64-bit Windows operating system and relatively powerful hardware. All software components involved in converting, exporting or viewing files must also be 64-bit. To recover damaged files, you should use Recovery Toolbox for Outlook https://outlook.recoverytoolbox.com/

To convert, you need to install this program and select the file you want to convert. Next, select the “Convert” button and specify all the data. Click “Save As” and specify the format (PST or any other). The process of reading data from a large 4GB file can take a long time, even if you have a powerful computer. The speed largely depends on the capabilities of the hard disk, RAM, and processor.

Why Choose This Program?

The main reason for choosing this software product is its stability. Many programs on the Internet perform similar functions. However, more and more users are using software from a trusted vendor capable of providing a quality product.

Thanks to this simple recovery tool, you can solve most of the problems associated with Outlook: mainly converting and viewing files. Similar products sell for relatively large sums of money, and some developers require you to pay a fee every month. A normal developer won’t ask for a lot of money for their work. He will simply provide quality software, and earnings will not be long in coming.

As for Ost Viewer, this option is quite popular among users. It contains all the necessary characteristics that make the program useful and in demand. If you want to use a good quality and stable tool, this is the perfect alternative.

What Other Options are There for Viewing OST Files?

We suggest looking at the two alternatives as a comparison. We will take a look at Free Outlook Ost Viewer and Kernel OST Viewer.

In the first case, you get a free software product that is used only as data viewing software. Distinctive features are the ability to open messages with attachments and the presence of a built-in scanner to detect corrupted data. This is a fairly simple version of the program. The user has the opportunity to improve the software for the Pro version to obtain an additional set of functions.

The second option is Kernel OST Viewer. The main characteristic of this program is its very simple interface. It is not so much a program as a tool. It allows just a few clicks to view the contents of the file. To do this, just select a file from the desired folder and select the conversion or viewing mode. This is a great option if you just want to view the file without additional steps.


You can of course use the two options above. They do an excellent job of their task. However, if you want to get a high-quality software product that will provide a comprehensive set of functions, try OST Viewer from Recovery Toolbox. It is capable of performing all of the above actions. This product works like a clock and that is why users like it. Try the free version and purchase the advanced version if you need more features.
