Background
I've designed a word template for a customer. It has a large number of nested quick parts that speed up his document creation process.
He is concerned that some of his employees may take copies of this when they leave and take them to a competitor. He needs each of his employees to be able to create new documents with the template and save them as pdf, but doesn't want them to be able to create copies of the template.
He has both on site windows servers with AD and also Office 365.
Question
What can I do to prevent people copying a dotx file, whilst also allowing them to use it to create new pdf documents?
