Repairing a damaged PST file is not a complicated task. But using a manual to do so can be a little complicated. Microsoft provides an inbuilt utility to repair damaged and corrupted PST files which is ScanPST.exe Outlook 2007 (Outlook 2007 utility is discussed here). But this utility works only for files whose file is not more than 2GB. If file size is 2GB or more than that, this ScanPST.exe outlook 2007 gets failed. So try a third party tool when file size large. A third-party PST scanning tool does not have any file size limitation and so it can repair files of all sizes. It can repair password protected PST files too. The tool allows users to save repaired files in EML, MSG, and DBX or in other file formats, to migrate recovered data to different destinations like Exchange server, Office 365 and Domino Server, and also to save emails to web mails like Yahoo, Gmail and Google Apps etc. Visit the below link: www.scanpstexeoutlook2007.net
