What is the best way for person to allow someone with 2012 to use macros. A few people in company have started using 2012 and they want tools that I have attached to buttons before in 2003. I know where I can put the buttons but I am trying to make simmilar where person either gets old message that this file has macro or use digital sig(which seems easier). If the person open the file with signature and then saves will that do it?
