Arranging Messages in Different Ways
As the number of messages in your Inbox increases, it can be challenging to prioritize them. You can customize how you view, arrange, sort, and group messages in Outlook to help you quickly determine which are the most important, decide which can be deleted, and locate any that need an immediate response. You can view only certain groups of messages, such as messages received in the last seven days, unread messages, or messages sent to a certain person or distribution list. You can also view a timeline of all your received messages. Outlook 2007 offers eight predefined views, and you can customize any of these to fit your needs.
