Our verdict on Kernel for OST to PST
Kernel for OST to PST is a Windows desktop utility for recovering and converting inaccessible, orphaned, damaged, or deleted Outlook OST data. It is aimed at Outlook users, IT administrators, and data migration specialists who need to restore mailbox content or move it into another format or service. Its emphasis is OST recovery rather than a broader set of mailbox file types, so buyers focused on OST files are the closest fit.
The recovery workflow includes processing multiple OST files in one operation, previewing mailbox items before saving, and filtering items by sender, subject, and date. It can recover deleted mailbox items and convert OST data to PST, with exports also available in EML, MSG, DBX, and MBOX. The vendor describes preservation of folder hierarchy and message metadata, and offers splitting converted PST files into smaller files. For teams moving mailbox data, supported destinations include Office 365, Exchange Server, Gmail, Yahoo, GroupWise, IBM Domino, AOL, and iCloud. These options give the utility a practical migration role beyond creating a PST file, though its scope remains centered on OST.
Pricing is a one-time $49 for the Personal License, intended for individual use; the Corporate License is $199 for business use within one organization; and the Technician License is $399 for consultants and multi-organization service use. There is no free plan, though the demo converts up to 25 items per folder. Email, chat, and phone support are offered, along with a 30-day refund period and 24/7 support. Choose it when batch OST recovery, preview, and multiple export routes match the task; look elsewhere if the requirement is PST or EDB recovery, or a non-Windows platform.
