This idea has been merged into another idea. To comment or vote on this idea, please visit IDEAMLCT-I-49 Right click on an link in a received mail should offer: Copy URL/URI Link.
In all other mail clients, you can right click on a hypertext link and choose: Copy URL. This is not possible in Notes. It should be. There is actually no easy way to get hold of the URL. I suggest this functionality be added in the next FP.
