Hi. I'm trying to generate pdf's using the mail merge feature in MS Word via the Acrobat PDFMaker Addin. I'm able to generate and send the pdf's without issue. The problem is that I can't restrict the recipients from editing the pdf's. I've set the security settings in the preferences menu (below). If I send a single pdf (no mail merge) it works fine. However, when I use the mail merge feature the document isn't encrypted.
It's the same problem reported here only none of what's suggested works for me.
