Thanks for the reply. Typing in a particular name, e.g. Richard Warprdrive will bring up Richard Warpdrive then suddenly and without any warning whatsoever, another name will pop up there in the list.
I'm learning Outlook will bring up other emails with that particular name in it that might have been from someone else. I'm also learning that Outlook is geared this way and seemingly no way to overcome it unless you have something else in mind. If so, please say on. Thanks!
