PCinfotools OST to PST Converter Review: Features, Performance, and Use
By Angus Trout 17-01-2026 14
A lot of individual users and businesses use Microsoft Outlook to send and receive email. It helps users keep track of their emails, contacts, calendars, and tasks. OST (Offline Storage Table) files are where Outlook keeps data from mailboxes that are not connected to the Internet. As long as the Exchange or IMAP account is still active, these files work perfectly. But users may not be able to get to their OST files if they have problems like an Exchange server going down, an Outlook profile getting corrupted, or accidentally deleting an account. When this happens, users need to convert OST files to PST format. This review focuses on the features, performance, and ease of use of the Pcinfotools OST to PST Converter to see how well it works and what it can do.
Why it's important to convert OST to PST
The OST files are linked to the Outlook profile that made them. Users can't open the OST file directly in Outlook
if the profile or server connection that it's linked to is lost. This can make it very hard for users who need to get to old mailbox data or important emails. Users can get their data back and add it to any Outlook profile when they convert OST to PST. They don't have to rely on the original Exchange environment.
Features and Capabilities
This tool will convert OST files that can't be opened or are orphaned into PST files without losing any of the mailbox data. It can convert all of Outlook's parts, like emails, attachments, contacts, calendars, tasks, journals, and notes. During the conversion, the original folder and mailbox structure is kept, which makes it easy to find and keep the data organized.
Thanks to a built-in preview feature, users can scan OST files and see what's in their mailboxes before they start the conversion. This lets users look at their data and pick which folders or items to export. Selective conversion is great for users who want to keep their output files small or only see important mailbox data.
The program works well with large OST files, so users can use it for both personal and business email. OST file support makes it possible for newer versions of Microsoft Outlook and Windows to read them.
Data and Performance Accuracy
When it comes to performance, the software gives results that are stable and reliable. The scanning process goes through the OST file very carefully and shows mailbox items right away. The speed of conversion is good and mostly depends on how large the file is and how the system is set up. Processing even large OST files is no problem at all.
The conversion makes sure the data is still correct. The formatting of the email, as well as the metadata like sender information, subject lines, timestamps, and attachments, stays the same after it is converted. Calendar entries, contacts, tasks, and other items in the mailbox keep their original properties. This makes sure that users get a PST copy of their mailbox data that is correct and can be used.
The user interface and how easy it is to use
The interface is clean, well-organized, and simple to use. A step-by-step workflow shows users how to select the OST file, scan the mailbox data, see a preview of the items, and save them as PST files. Users who aren't very tech-savvy can still finish the process without any problems.
Users don't have to change much, which makes things easier and saves you time. The tool is easy to use for both users who are new to IT and users who have been working in IT for a long time because the options are clear, and the navigation makes sense.
Real-Life Examples of Use Cases
This tool for converting can be useful in many situations. IT admins can use it to get mailbox data back after an Exchange server crash or to read emails from accounts of users who used to work there. Users who move Outlook data to a new system or profile may need it. It is also helpful in legal, audit, and compliance situations where email data needs to be stored or accessed separately from the original server.

The PCinfotools OST to PST Converter is a good and safe way to convert OST files that you can't open into PST format. It has a lot of useful features, it converts data correctly, and it's easy to use. This tool is a good choice for users who want to convert OST files to PST files in a smooth and reliable way.
