The major updates in MS Outlook 2013 include previewing messages in the list and quicker response with inline replies. With the previews, the users can figure out the messages from the list itself without having to go through the details. Ignoring as well as responding to the emails is quicker and easier with this feature. Another update, which makes replying to the mail sender faster is related to inline replies. This acts like a real-time chat and directs the user to the new box with just one click.
