Thank you Anjlua for the effort. I'm not sure what version of Outlook you're using but it does not coincide with what I have here. Therefore I am unable to find "Click on Arranged By and select E-mail Account" so have to leave it with "by date" although I have tried "from" and others in the list.
At first, I thought you had it. But after trying it on a few names, it still brought up two others that I was not searching for. It took part of the name and then ending of another email address and therefore mixed the names up again.


Good try though & overall, I'd say what you have suggested works better than other ways I have tried. Thanks again for your efforts and help.
