How to fix Office 2007 attachments downloaded as zip files
Few times I have found a small but annoying issue on Maximo when attaching Office 2007 files. Do you know those Excel, Word, PowerPoint files with xlsx, docx, pptx extensions? Yes, those!
If you are using Microsoft Internet Explorer it may happen that these files can be uploaded successfully into your DOCLINKS folder but when you try to retrieve them they are downloaded as zip files.
If you have this problem here is the solution for you.
Edit httpd.conf file of your IBM HTTP Server (look in the conf subdirectory) and add the following section at the end of it.
AddType application/vnd.ms-word.document.macroEnabled.12 .docmAddType application/vnd.openxmlformats-officedocument.wordprocessingml.document docxAddType application/vnd.openxmlformats-officedocument.wordprocessingml.template dotxAddType application/vnd.ms-powerpoint.template.macroEnabled.12 potmAddType application/vnd.openxmlformats-officedocument.presentationml.template potxAddType application/vnd.ms-powerpoint.addin.macroEnabled.12 ppamAddType application/vnd.ms-powerpoint.slideshow.macroEnabled.12 ppsmAddType application/vnd.openxmlformats-officedocument.presentationml.slideshow ppsxAddType application/vnd.ms-powerpoint.presentation.macroEnabled.12 pptmAddType application/vnd.openxmlformats-officedocument.presentationml.presentation pptxAddType application/vnd.ms-excel.addin.macroEnabled.12 xlamAddType application/vnd.ms-excel.sheet.binary.macroEnabled.12 xlsbAddType application/vnd.ms-excel.sheet.macroEnabled.12 xlsmAddType application/vnd.openxmlformats-officedocument.spreadsheetml.sheet xlsxAddType application/vnd.ms-excel.template.macroEnabled.12 xltmAddType application/vnd.openxmlformats-officedocument.spreadsheetml.template xltxSave the httpd.conf file and restart the HTTP Server.
Now you should be able to download those files without any problem.
Here is the original article where I have found the solution.
UPDATE! John spotted an IBM TechNote describing the official solution.
