How do I quote email content and send a message to internal colleagues in V5?

1. Select the email thread you want to work with from the discussion list on the left. 2. Find the email you want to quote, then click "Quote" (the double quotation mark icon) in the toolbar on the right side of the message. 3. Check the quoted content in the "Enter Message" editor at the bottom and add an explanation for your colleagues. 4. Confirm that the editor shows "Only visible to colleagues", then click "Send" at the bottom right to send the quoted content and your explanation to the internal discussion.
