Register Office 2007 file format MIME types on servers
In order for servers to recognize the new file formats in the 2007 Office system, you will need to register the Multipurpose Internet Mail Extensions (MIME) types for each new file type. If the MIME types are not registered, servers will detect the new file formats as ZIP archives. MIME types are automatically registered with computers running Windows Server 2003 Service Pack 2 (SP2) or later versions.
For servers running Windows 2003 Server and Internet Information Services (IIS) 6.0, you can add the Open XML types in IIS Manager | Server Properties | MIME Types. IIS 7.0 includes these new MIME types by default.
For servers that are not Windows-based, you will need to register the MIME types manually. Please refer to the product documentation for your server or refer to the links at the end of this article for more information about registering MIME types.
The following table shows the extensions you will need to register, their file type, and their MIME type:
