Office 2007 Mime Types (for IIS)

Had some troubles with Office 2007 files not being downloadable on our windows servers … did a bit of Googling and found this nice list of Office 2007 mime-types:


Adding all mime-types to IIS in one step is very simple:

The easiest way to do this is stopping IIS and editing the metabase XML file (C:\WINDOWS\system32\inetsrv\MetaBase.xml) using a text editor. Search for the <IIsMimeMap Location="/LM/MimeMap" …> element and append the lines above to the MimeMap attribute

    Excellent article! Thanks for the help.

    MIME types can be edited though IIS by right clicking on the webserver, selecting properties, then pressing the MIME type buttons. You will need to restart IIS after making the changes, this can be done by running “restartiis /noforce” from the start button, then run.

    I’m trying to do this on IIS 5.0 – WIN2K3 and there is no xml file, only C:\WINNT\system32\inetsrv\MetaBase.bin which is considerably less editable! When trying to do it through IIS, I’m clicking File Types in the HTTP Headers tab, Clicking New Type, putting “xslx” (tried .xslx too) into Associated extenion and “application/vnd.openxmlformats-officedocument.spreadsheetml.sheet” into Content type (MIME). Then restart IIS and nothing… any ideas anyone?

    @Phil I don’t know the IIS settings, but try “xlsx” instead of “xslx”

    Really love your layout.
    @Phil, try to back up your metabase to add the MIME types manually
    and if you’re brave (I haven’t tested it),'s IIS script. If you have time to kill, try the script – otherwise stay safe and do it manually. 😉

  20. My problem is that, while HTTP response gets delivered correctly to the browser (encoding is preserved and file is CSV), Excel shows it as gibberish text. I don’t know why. I added these MIME types, but still no result.

    Once again, it worked, thanks for clear instructions.
