I have a number of Office 2007 documents (.pptx, .docx, .xlsx) in a SharePoint document library and when user tries to open the documents, it tries to open as a zip file. This happens to some users, but not all.
I posted this issue at http://superuser.com/questions/110211/why-office-2007-documents-open-as-a-zip-file, but I failed to mention that it was related to the Sharepoint so it got moved to the superuser.com
Please help.
