You may already know that when you see the plus or minus sign to the left of a group of emails, notes, or other listings within Microsoft Office, it means that you can expand or collapse the group to either view or hide the contents.

In addition, by choosing View on the standard toolbar, you can choose to expand or collapse ALL listings.

From View, click on Expand/Collapse Groups, and then slide over to again choose your preference from several options.

Particularly helpful when faced with a group of 700 emails, a click of your mouse on this feature can put YOU in control of how you view (or act upon) them.
