Abrupt interruptions during active Outlook sessions are among the most common triggers when trying to recover PST file corrupted after sudden power outage or system crash, since the PST file doesn’t close cleanly when the system shuts down mid-operation, leaving ongoing write processes incomplete and the file structure in an inconsistent state. Making a bit-for-bit copy of the corrupted PST file before attempting any repair is an essential first precaution — running any repair tool directly on the only copy of a damaged file risks worsening the corruption if the process fails partway through. Running ScanPST.exe against the copied file addresses minor write-interruption corruption effectively, but power outage scenarios frequently cause deeper structural damage that extends beyond what the Inbox Repair Tool’s single-pass scan can reconstruct. Checking Windows Event Viewer for disk I/O errors logged at the time of the crash helps determine whether the corruption is file-level or whether it originated from storage hardware damage that needs to be addressed before attempting any PST repair. The SysInfo PST File Recovery Tool handles crash-related corruption through three recovery modes — Standard, Advanced, and Deep — with the Handle Alignment Errors option specifically targeting header-level damage that commonly results from improperly terminated write operations. The snapshot feature saves scan progress for large files affected by extensive crash damage. Compatible with all Outlook versions and Windows versions including Windows 11.
