  • The computer has been infected with a virus. A virus could have quite possibly got onto your system, whether it was through a website or email and corrupted important system files, many of which may be required by Outlook for proper functionality.
  • The computer shut down incorrectly. When the computer is shut down incorrectly, it can sometimes lead to data corruption. These damaged files may in some way be linked or required by Microsoft Outlook.
  • A hardware component is either damaged or incorrectly configured. A failing power supply unit can damage application files or it could be damaged sectors on your hard drive, prohibiting not just Outlook by various other applications from running correctly.
