When a corrupt PST loaded, all content which is still readable inside the corrupt PST file will be displayed.

Outlook PST Repair v4.5 has been designed to look like Microsoft Outlook to provide users and administrators with a familiar user experience. Data which has been lost due to corruption is gone, no tool will be able to recover this.

All content within the corrupt the PST file which is in its valid state can be recovered. I questioned this with Stellar Phoenix as 100% of corruption is a big claim however the company was confident to back it. Stellar Phoenix claim that their tool Outlook PST Repair v4.5 can repair a corrupt PST file and bring it back to a consistent state regardless how severe. PST files with severe correction or PST files where the indexing table is completely removed, ScanPST will not repair the file. Stellar Phoenix labs performed testing with ScanPST and from their testing they discovered that the free PST repair tool is capable of repairing PST files with only minor structural errors.
