Hello. I work as an I.T. Support Specialist at a large company. We have a domain "Intranet" setup that all employees can view work related documents and Excel documents. The person who updates the Intranet ran Microsoft Office 2003 in the past and could create documents and then Hyperlink them onto the Intranet as .doc or .xls files. Now, he has upgraded to Office 2007 and publishes the files in the formats of .docx and .xlsx files types. For some reason when clicking on a Hyperlink document in the Intranet that goes to a .xlsx file type, it will not open the file and displays a "Page cannot be displayed message". We are both sure that the files exist on our Intranet server, but he and other employees are not able to open the .xlsx document type and can only open .doc & .xls. Any help here guys?
