In Gmail what does the following mean in the Inbox:
Where can I change the setting?
This is an interesting message because what you’re talking about is one of the more desireable features of Google’s Gmail service, from what I have heard from users. It’s how Gmail keeps your discussions in “threads” (actually, Gmail calls it “conversations”, but threads is a more common name for the capability).
What Gmail is showing you here is that someone named Dave sent you a message, then you responded. Both of those messages are viewable simultaneously, and there are a total of 2 messages in that thread.
Here you can see that Marissa and I have been sending mail back and forth for a while: there are 11 messages in our conversational thread, the first of which was from her and the most recent of which was from me. The little paperclip by the date also shows that at least one of the messages in the thread has an attachment. The word Nintendo is the subject of the message and the first few words of the most recent message in this thread are “I have attached a release with more info…”
If I open up the message, note how Gmail has a slick presentation of the entire discussion thread and an all-important “Expand all” if I want to see all of every message rather than just the most recent:
As to your question, I don’t believe that there’s any way to turn this feature off, but since it’s such an integral part of Gmail and so darn useful, I suggest instead that you might spend a few weeks trying to get used to it. Once you’re comfortable with it, I think you’ll find it a very elegant way to keep track of your email discussions.
