Useful MIME types

Web Bureau

Useful MIME types for Microsoft Office documents:

You upload a file to your CMS via your rich text box but you get a 404 error.

The solution to this is Internet Information Services (IIS)


Out of the box, IIS6 only accepts requests for known MIME types. Since Office 2007 was released after Windows Server 2003 and IIS6, IIS6 knows nothing about the new MIME types. So you need to manually add them:

    Open Computer Management. (Right-click My Computer… Manage…)
    Right-click Internet Information Services (IIS) Management… Properties…
    Click MIME Types…
    Click New… and add the following:

.docx application/vnd.openxmlformats-officedocument.wordprocessingml.document
.xlsx application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
.pptx application/vnd.openxmlformats-officedocument.presentationml.presentation
