Use the Plain Text MIME Option

If a mailbox-enabled user cannot interpret HTML, select the MIME encoding option, Provide message body as plain text. When this option is selected, a message body is composed of text only. Graphics and active links are replaced with textual representations. Character formatting, such as bold, underline, and color is not retained.

Important   When you select the MIME encoding option, Provide message body as plain text, you can also select the Use Microsoft Exchange rich-text format.
