I tried but no avail. I note that the article refers to 2007, but I don't think that is a problem at this time. I am ( or have convinced myself) that it will need an uninstall and a reinstall of Outlook to fix the problem. Normally one can repair a damaged item, but to repair just the look of part of the home page may not be possible.
I can and do use Outlook, so it is a "niggle" rather than a problem.
At this point in time I will leave it and when I get the desire, I will reinstall outlook.
Thank you for your time and help. Have a nice day
