I have a very frustrating problem with a single users email account. They are unable to double click and open any attachments in Outlook and you cannot right-click and select open in the drag down menu. There is no error message at all, the hourglass appears for a second and then nothing.
You can preview the attachments and you can drag to the desktop and/or save them and open them.
I have tried the various other solutions on this site for similar issues. I cleared out the temp folder, No google desktop installed, Internet Explorer is the default browser, I have repaired Outlook and reinstalled Outlook, I even did a repair install of Windows XP. Nothing seems to work. Any suggestions would be helpful.
