Hi guys... For those who need this functionality you need to modify the emailmessage column to be text instead of nvarchar with 4000 characters and then you need to modify the add and update stored procedures.
I have created a quick SQL script to do this for you.
The disclaimer is: This is for Dynamic Forms 2.5 release only and this is assuming your site does not need object qualifiers.
To make this modification you can download the attachment and open the txt file in notepad. Copy and paste the SQL Query under Host, SQL and click to execute the SQL script.
We will also review this in the future to determine if this should be changed for all installations automatically.
