You can set up Web Messaging so that when you read a message, the menu buttons (Next, Reply, Reply All, Forward, Delete, and Move To) are located only at the top of the page, only at the bottom, or at both the top and bottom (if the message is long).
From the Options and Styles... menu, select Preferences under My Options.
On the User Preferences page, locate Menu buttons in read message screen and select Top, Bottom, or Both.
Click the Save button.
