Resolve 'Scanpst.exe Fatal Error 80040818'

Microsoft provides a tool called Scanpst.exe with MS Office package which is efficient enough to fix the corruption of PST file. As its name suggests, this tool examines the corrupted and damaged PST file and tries to repair it. This tool checks the PST file directory structure and analyzes the headers of all mail items. But this tool is not always effective as most of the PST issues remain unfixed after using this tool. In order to resolve those files either backed up PST file need to be restored or any third party software need to be used.

To understand the situation lets consider a scenario where when PST file of MS Outlook 2007 gets corrupted and attempt was made to repair the PST file using Scanpst.exe tool, the tool fails to repair the corruption and in addition an error message is thrown. The error message thus thrown is mentioned as below –

"Scanpst.exe fails with Fatal Error: 80040818"

The possible cause of this scanpst fatal error of the PST file has been brought from the earlier version of Outlook to Outlook 2007. Actually, MS Outlook 2002 and its earlier versions uses ANSI format of the PST file whose size is limited to 2GB and same is the case with the Outlook 2003. But the Outlook 2007 supports the Unicode format of the PST file whose file size is extended to 20GB. So, unless the Windows registry is modified to give away the size warning for the PST files the warning message will continue to flash about the large PST size that Scanpt.exe can not repair.

In order to overcome this scanpst fatal error 80040818 issue the PST file size need to be reduced. The PST file size reduction can be done by removing the unwanted and useless data’s from the PST file, by compaction of the PST file or by empting the ‘Deleted Inbox Items’. But if the issue still persists and PST remains corrupted then in order to resolve the issue the only way is to use any third-party software like PST Repair. This tool effectively repairs the corruption of the PST file which is not possible with Scanpst.exe tool. So, use this tool and avoid scanpst fatal errors.
