I tried to add a column to my Inbox. It did not like the column I chose. Now when I try to open my inbox, I see a blank screen that says: "Unable to display the folder. Could not complete the operation. One or more parameter values are not valid". I would be more than happy to remove the offending column heading if I could find it. Can anyone help? The Inbox will not allow itself to be deleted and recreated as far as I can see. (Office 2k sp3, Win2k sp4, logged in with administrator rights).
