To help you organize information, Outlook 2007 allows you to customize various message folder views. By default, Outlook 2007 displays only a small selection of columns for messages, including the From, Subject, Received, Size, Flag, Attachment, and Importance columns.
For details on how to add and remove columns from a folder view to show more or less information about your messages, see "Working with the Standard Outlook Views" in "Working in and Configuring Outlook," one of the bonus chapters available on the companion CD.
You can easily sort messages using any of the column headers as your sort criterion. To view messages sorted alphabetically by sender, for example, click the column header of the From column. To sort messages by date received, click the column header of the Received column. Click the Attachment column header to view all messages with attachments.

Whereas sorting allows you to arrange messages in order using a single column as the sort criterion, grouping allows you to display the messages in groups based on one or more columns. For example, you might group messages based on sender, and then on date received, and finally on whether they have attachments. This method helps you locate messages more quickly than if you had to search through a message list sorted only by sender.
Grouping messages in a message folder is a relatively simple process:
