Summary
Microsoft Outlook users often work with OST files to access mailbox data offline. However, when an Outlook profile becomes unavailable, an Exchange account is disconnected, or an OST file becomes inaccessible, users may need to convert the OST data into a PST file for backup, migration, or further access.
DataVare OST to PST Converter Expert is a dedicated utility designed to convert OST files into PST format without requiring Microsoft Outlook to be installed. According to the vendor, the software can export emails, contacts, calendars, notes, tasks, journals, and other mailbox data while retaining the folder structure.
In this review, we will look at its key features, conversion process, compatibility, advantages, limitations, and overall usability.
What Is OST to PST Converter Expert?
OST to PST Converter Expert is a Windows/Mac-compatible software solution for converting OST files into Outlook PST format. The application is intended for users who need to access or migrate data stored inside OST files.
One notable feature is that the software works as an independent application, so Microsoft Outlook and Exchange Server installation are not mandatory for performing the conversion.
The software can also be used with specified OST files selected from local storage, allowing users to choose the source file and output location before starting the conversion.
Key Features of OST to PST Converter Expert
1. Convert OST to PST
The primary function of the application is to convert OST files into PST format. The vendor states that the software can migrate mailbox components including emails, contacts, calendars, notes, tasks, and journals.
This makes the tool suitable for users who want to move OST-based mailbox data into a PST file that can subsequently be used with Outlook.
2. Conversion Without Microsoft Outlook
One of the notable benefits is that Microsoft Outlook does not need to be installed for the conversion process. The software operates independently and can export OST data directly to PST.
This can be useful when the original Outlook profile or Exchange connection is no longer available.
3. Selective OST File Conversion
Users can browse their computer and select the specific OST file they want to process. The product page also mentions a file-filtering capability for locating OST files from local drives.
This gives users more control over which source file is processed instead of having to work with an entire collection of files.
4. Maintains Folder Structure
According to, the application retains the folder structure while exporting OST data to PST. This includes mailbox components such as emails, contacts, notes, journals, and events.
Maintaining the original structure can make the resulting PST file easier to navigate after conversion.
5. Supports Multiple Outlook Versions
The software's product page lists compatibility with Outlook versions including 2003, 2007, 2010, 2013, 2016, 2019, and 2021.
This makes it relevant for users working with both older and relatively newer Outlook environments.
6. Local Output Location
After selecting the OST file, users can specify where they want to save the converted PST file. The application allows users to choose an existing folder, subfolder, or create a new destination folder.
This is useful when users want to organize converted files separately from their source data.
7. Support for Large OST Files
The vendor's FAQ states that the application can scan and export Unicode OST files up to 50 GB, while also noting that a maximum of one OST file can be scanned/exported simultaneously.
Therefore, users handling large mailbox files should consider the stated file-size and single-file processing limitations when planning a conversion.
8. Windows and Mac Support
The product page lists support for Windows and Mac operating systems. For Windows, the listed systems include Windows 11, 10, 8.1, 8, 7, XP, and Vista. The page also lists multiple Mac OS versions.
