SysInspire OST to PST Converter review
A focused, low-cost Windows tool for OST recovery, conversion, and export.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SysInspire OST to PST Converter is Windows desktop software for recovering damaged or deleted Outlook OST mailbox data and converting it to PST and other formats. It is aimed at people who need to retrieve mailbox items from an OST file, preview content before export, preserve folder structure and message properties, or move selected folders into another format or Office 365. The vendor states that Microsoft Outlook installation is not required for OST recovery and conversion. Integrations listed for the product include Office 365, Gmail, and Yahoo.
According to the vendor's pricing page, the paid version costs $29 as a one-time purchase. The published plan includes OST recovery and conversion, previewing mailbox items before export, and export to PST and other formats. The product also supports EML, MSG, MBOX, HTML, VCF, and Office 365 output, along with selective folder conversion and date-range email filters. A demo is available, with the product page limiting it to 25 items from each folder. This makes the pricing straightforward for a defined recovery task, while users needing unrestricted export should choose the paid version.
The standout strength is its focused OST workflow: it can search drives for OST files, recover corrupted and deleted mailbox items, preview results, and retain folder hierarchy before export. That focus may suit Outlook data recovery better than a general-purpose migration tool when the source is specifically an OST file. However, it is Windows-only and remains centered on OST recovery and conversion. Choose it for a low-cost, one-time OST-to-PST or multi-format export workflow; choose an alternative if you need broader platform coverage or recovery beyond OST files.
