sharonmiller Posted January 31, 2018 Report Share Posted January 31, 2018 Our office recently upgraded our Nitro to Nitro Pro. Since then when we open any PDF attachment from our Outlook we get a pop up saying "you should only open documents from a trustworthy source....." with the option to click off the the pop up grayed out. Does anyone know how we can turn these off? Much appreciated. Link to comment Share on other sites More sharing options...
