MS Outlook stores all your email messages, contact information and other objects in a single file known as Personal Folders File (PST). This file is stored on your local hard disk and carries the name 'Outlook.pst'. As this PST file grows in size gradually, it becomes susceptible to corruption. Corruption takes place if the file exceeds a predefined size limit of 2 GB (For MS Outlook 2002). Other potential causes behind PST File corruption include, virus infection, application errors, hardware errors, etc. As a consequence, all your vital email messages, personal contacts, calendars, notes, and other items in the PST file would become inaccessible. To effectively overcome this problem, you need to repair outlook with reliable mechanism.
For instance, when you start MS Outlook and try to access a mailbox folder, you may receive any of the following errors on your screen:
“OUTLOOK caused an invalid page fault in module Emalscan.dll at 0137:10004d3a”
