  Microsoft Outlook is an email application that lets you send and receive emails as well as manage appointments on the application's built-in calendar. The application stores your personal information, emails and folders in a file known as the Personal Folders File (PST). The PST file steadily increases in file size each time you send and receive emails or enter appointments. Over time, the PST file becomes corrupt and needs repairing. There are a number of repair tools available for recovering a corrupt PST file.
