About

WholeClear OST to PST Converter provides a convenient way to convert Outlook OST files into PST format while giving users control over the data they want to process. Its modern graphical user interface makes the available functions easy to navigate, helping users select conversion settings without unnecessary steps.

The software shows a complete preview of mailbox items so that users can verify their data before doing the conversion. Depending on their needs, they can process the whole mailbox or select specific emails instead of converting everything. This selection flexibility is useful for generating email backups, transferring important messages, or keeping mailbox records.

For users with huge numbers of emails, the OST to PST Conversion provides PST splitting options based on file size; it can make it easier to store and handle. The automatic structure maintenance tool keeps the original mailbox folder structure, so your converted emails are organized and easy to find. There are an additional 19 language options the application provides for various user preferences. It runs on Windows, Mac and Linux Systems.
