how can i view emails from a sender into one page instead of individual pages
Can you clarify what you are trying to do? I don't quite get the question.
Some times you exchange more than one email with another person - i'd like to be able to see all the messages on one page as I could in the old format. You could just scroll down to see the conversation that was posted previously.
At the top of the message list click on "Sort by". The last item in that menu is "Conversations". Do you have it checked?
