I found out that this is possible with an expression field, with the formula like below and use a domain with control type HTML.
font-family: Calibri, Tahoma, Arial;
' + REPLACE(REPLACE(REPLACE(t1.message_body, '<', '<'), '>', '>'), CHAR(10), '
') + '
It is nice, but it does not fully give the desired output.
