Send HTML letter with MAILTO

Hello everyone. I want to send HTML letter with MAILTO button.

I wrote simple java script. It works on page, but buttons don’t work, when I use Send Exchange Mail Message. (Outlook Mail).

I’ll be glad if you had fast solution.
I suppose, I can do it using MIME. If you have short guide of MIME, send it to me, please.

function OutlookCorreсt(){";

<*th onclick=“OutlookCorrect();” align=“center” bgcolor=“3cb371” width=“50%”>



To start with Is the property ISBODYHTML enabled in Send exchange mail activity

Cheers @YoungFave

It’s enabled
