Microsoft outlook comes with a utility named Inbox Repair Tool. The tool is useful when you are unable to open the Personal Folder File i.e. .PST files that are the data file for Microsoft Outlook. These PST files contain all the user information and files that are stored by user in Outlook. The PST files can be assigning by you to be the default delivery location for e-mail messages. You can use a .pst to organize and backup items for safekeeping.
If you are having problems while operating on Microsoft outlook then the possible reason can be the corruption in the PST file that has the entire data present on it. When PST get corrupted you will face problem accessing the email messages. You feel that the inbox has been corrupted. In this situation Inbox Repair Tool (the utility that comes with Microsoft Outlook) need to be used. Its executable file is named as Scanpst.exe and it is also known as Scan PST utility.
Scan PST utility is installed when you install outlook and its installation location is
< system drive:>\Program Files\Common Files\System\MSMAPI\LocaleID
LocaleID is the the locale identifier (LCID) for the installation of Microsoft Office. The LCID for English - United States is 1033.
When it starts scanning the selected PST file then it scans them to find the errors and corruptions. It checks whether the physical structure of the PST file is intact or not. If it is not intact and the corruption is in the header part of the file then the Scan PST Utility starts to correct them to make the physical structure intact once again.
It performs the corrupted header repair very well but if the corruption is in the actual data then it is unable to repair it and treats it like a damaged and unrecoverable file. So this kind of file is deleted by it and this may cause you a big loss if the files are necessary for you. It is the very big limitation of Inbox Repair Tool that is still unresolved by Microsoft.
