>BTW, once we switched to Outlook exchange, UT News letters start to come in incorrect format, e.g. I see nothing in the body of e-mail. I guess, I have to adjust some settings in Outlook, but haven't figured this out yet...

I thought I had something in my code to detect that default client but it is only about sending to the default client and not returning which one it is.

As for the Universal Thread question, we don't have any newsletter. Can you clarify on what you are referring to?
