I have MS Office 2007 installed. When am using Outlook Web Access and I receive MS Office 2007 attachments from some colleagues, OWA requires me to save the file, rather than it opening with a double-click. When I "Save Target As..." it gives only the option to save as "Compressed (Zip) File" even though the filename appears as "filename.xlsx" Then, when I open the saved folder, the filename does not appear anywhere. Ideas?
