When you attempt to view a message that contains Rich Text Format (RTF)or Enriched Text Format (ETF) text, the text may not be visible or it mayappear as an attachment. RTF information encapsulated in a Winmail.datfile may appear as a .dat attachment, or may not be visible. You cannotsee embedded objects in the message, although you can see fileattachments.
Outlook Express does not support .rtf files, .etf files, Winmail.datfiles, or embedded objects in messages. Outlook Express cannot displayRTF or ETF text.
To work around this issue, use one of the following methods:
Request that messages with RTF and ETF text be sent as attachments.
Request that messages be sent with standard formatting.
Microsoft Exchange supports and uses RTF. Messages sent to Microsoft Mailrecipients have the RTF information encapsulated in a Winmail.datattachment file.
