I have used the HTML Upload Wizard to load an HTML Email Template. Everything is going well except I want to be able to lock down the code and enable only certain areas for editing. It will only allow me to view in Standard mode.. I don't have an option in the gear drop down to enable Protected Mode. This thread Email Upload Template feature (new) - help! seems to answer how to enable field editing, but that's assuming that the Template is in Protected Mode to begin with.. my entire Template is editable.
How do I get into Protected Mode?
