I tried the 1st registry change suggested by CharlieG100 although this didn't seem to work.
For those doubting though the steps show by ¡Firedog worked fine and I have little knowledge of registry changes and managed to implement it within a minute.
I am now back to sending emails with links in. Thanks!!
Sorry for the confusion, Mick - DLC. The solution was not mine. I had read the solution by Hoge and the clarification by iFiredog and my brain took a few moments for the steps to be clear (Dementia setting in?). So, I attempted to repeat the solution in what I thought were clearer steps -- guess I failed. Again -- sorry.
