Final answer:
Outlook 2010 introduced the new Conversations View, which groups related emails together to declutter the inbox and streamline email management.
Step-by-step explanation:
The view that is new to Outlook 2010 is the Conversations View. This feature allows users to see related emails grouped together for easier tracking of discussions and threads.
This is a significant change from earlier versions of Outlook, which did not have this functionality. The Conversations View helps to declutter the inbox and makes email management more efficient by grouping messages with the same subject line into a single thread.
