Change the message format to HTML, Rich Text Format, or plain text
You can use RTF when you send messages inside an organization that uses Microsoft Exchange, but we recommend that you use the HTML format. In fact, when you send an RTF message to someone outside your organization, Outlook automatically converts it to HTML, so the message keeps its formatting and its attachments.
