Internet-style quoting consists of putting a > or other character in front of the original message when you reply or forward it. Recipients can easily distinguish the original message from your comments. This method is preferred on many Internet mailing lists that transmit in plain text only
The default setting in current versions of Outlook in no quoting, no indentation. This can be changed to use a quote prefix, indent quoted messages, or attach quoted messages. We do not recommend using the Indent or Attach options.
Note that the quote prefix character (usually ">") is applied only to plain text messages. When you enable this option and reply to an HTML message, the quoted message is prefaced with a blue line.
