Are you using Microsoft Outlook or Outlook Express? These two are very
different programs where one can handle Rich Text messages (Microsoft
Outlook) while the other cannot. The common message formats between
Microsoft Outlook and Outlook Express is Plain Text and/or HTML. Therefore
I would double check with the sender to verify that they sent the message in
Plain Text or HTML.

ps - there are other factors that can cause a plain text or html formatted
message to switch to Rich Text when the user clicks the send button.
