That's normal and expected behavior, given that AppointmentItem bodies are
RTF, not HTML.

See http://www.outlookcode.com/article.aspx?id=31 for your options. If you
need more specifics, we'll need your Outlook version.

I am tring to dynamically build a body of an appointment via a custom built
AddIn.

Does anyone know how I might be able to pass markup into that property and
have it render on the appointment?

ie.
Outlook.Appointment.Body = "bHello World!/b"

renders exactly as it's entered into the string
