Outlook Tasks Body field - how to set formatted text programmatically?

Question

Hello.

I would like to know more about Outlook Tasks Body field (place where you put formatted text inside) - I assume it uses RTF to render it? (Because I tried using html, it didn't render, it just outputs tags in plain text).

Can I change it so Outlook would render Html?

I`m trying to sync outlook against some data using this Stssync provider
