Some of my emails are hidden in threads from previous conversations and not showing up as the last email received. If I am not expecting an email then I may never see it unless I happen to open up a previous that could be weeks earlier. I hate this and cannot conduct business when I can't see emails coming in . If someone is replying to a previous email , I may never see a new conversation. Only if someone sends an email that is not a reply am I guaranteed to see it. How do I fix this
