That's pronounced MO-ICE. It stands for Microsoft Office Isolated Conversion Environment, and yes, you should have it.
What MOICE does and why you need it
MOICE uses the converters in the 2007 Office release to convert Microsoft Office binary format files (used in Office 2003 and earlier) into the Microsoft Office Open XML format. This process helps to remove the potential threat that may exist if the document opens in the binary format. MOICE converts incoming files in an isolated environment to help protect against potential security threats.
This helps prevent malicious attacks using potential security vulnerabilities in legacy file formats.
