Document will only open in read-only mode
I created a .pdf document from a Word document in Adobe Acrobat Professional 10.1.1. When I open the .pdf it will only open in read-only mode. I want to change the security settings to prevent editing before I send it out but the File>Properties>Security>>Security Method is greyed out and set to "No Security." I have tried certifying and signing the document and even placing in a secure envelope with no luck.
Help.
Thanks in advance.
