Hello, I have two questions, please move it if it is in the wrong spot. We run Outlook 2011 on our iMac's here at the office. 1. is there any way to default Acrobat 9.0 for opening a pdf in an email? It always opens in Preview, can this be changed? 2. lately we have been receiving pdf's and when they are opened in Preview they are blank, but if we open them in Acrobat 9.0 or higher then they are viewable. Is there a feature in Preview that can override this. Any suggestions would be great. Thanks in advance.
