This policy setting allows you to control how plain text messages are formatted when they are sent from Outlook. If you enable this policy setting, text is automatically wrapped in Internet e-mail messages and attachments are encoded in UUENCODE format. If you disable this policy setting,  Outlook uses the standard MIME format to encode attachments in plain text Outlook messages. Users will not be able to change this configuration. If you do not configure this policy setting, the behavior is the equivalent of setting the policy to Disabled, but users can modify plain text options in Outlook when required by clicking Tools, clicking Options, clicking the Mail Format tab, clicking Internet Format, and changing the values under "Plain text options".
