If you have set up Web Messaging so that the original message is included in your replies, you can also flag the lines of the original message with the "> " (greater than) symbol. (This will visually distinguish the contents of the original message from the contents of your reply.)
Select Edit My Preferences under Personal Account Options.
On the Edit Preferences page, locate Reply message (original message indicator) and select " >".
Click the Save button.
Note that if you select ">", but have not selected Include original message under Replying, the original message will not be included or flagged.
To exclude ">" (greater than) symbols from your replies:
Select Edit My Preferences under Personal Account Options.
On the Edit Preferences page, locate Reply message (original message indicator) and select " > ".
Click the Save button.
Note: This setting stays in effect (for each message you send) until you reset it.
