Thanks 124 very useful information which has been "stored".
The problem has been resolved. I was "allowed to look at the new set up". Hmmmh could not believe that the owner of the laptop concerned had done such an elementary error. Spelling his email address incorrectly so many times (nearly 2 hours) after using it for 10years!
Imputting the correct spelling, and he is off.
Thanks again for courtesy of reply
