I tried that yesterday and it didn't work. I have tried again via the link, but once you complete the data it takes up to 24 hours for them to come back to you. It doesn't matter what I try they still want to take you to an defunct email address.
Richard.. Thank you for being helpful. I appreciate that microsoft take their security seriously. I shall follow the above procedures and get back to you, though as you say it may take 24 hours.
