MOSS 2007 is a part of the Office 2007 suite of products, which includes client applications such as Microsoft Office Word 2007, Microsoft Office Excel 2007, and Microsoft Office Outlook 2007. MOSS 2007 and Office applications are designed to seamlessly work together.
Office applications support new file formats that are based on open XML standards such as files that may or may not include macros. For example, you can save Word 2007 documents that contain macros as .docm files and those that do not contain macros as .docx files. MOSS 2007 supports both versions, and this helps in storing Office files in different formats in MOSS 2007. This makes it easy to reuse content such as text, charts, calculated values, slides, and other objects, which helps you save time.
