Jurgen Wildhagen 0 Report post Posted December 17, 2018 Hi, We've got a lot of PDFs with attachments. Every time I open one with Nitro, it asks me for confirmation to open it. If i confirm this, all opens OK. But the next attachment, it again asks for confirmation. Is it possible (i.e. via a registry key) to remove this confirmation and just open it when I doubleclick on an attachment in a PDF? Regards, Jurgen Share this post Link to post Share on other sites

Are you referring to how to disable the "You should only open attachments from a trustworthy source" warning in Outlook as shown below?: Thank you very much in advance and I am looking forward to hearing back from you.

Jurgen Wildhagen 0 Report post Posted December 19, 2018 hi @AllainU Thanks for your reply. No, I meant this popup: It is in Dutch. but it says "Do you want to open this attachment?" It happens when we open an attachment in the PDF itself. The opening of the PDF itself is working just fine. Regards, Jurgen Share this post Link to post Share on other sites
AllainU 0 Report post Posted December 19, 2018 Hello @Jurgen Wildhagen, Thanks for your response and for providing the screenshot of the message you're receiving. Yes, you can turn this option off and to do so, open up Nitro Pro and go to, "File > Preferences > Notifications" and uncheck the option, "Show In-Product Messages". Thanks for choosing Nitro Pro and I hope this helps! Share this post Link to post Share on other sites

Hello, Sorry for digging up this old thread but I do however struggle with the above issue. Is there a known fix for this? I know I could open up Outlook as administrator and uncheck it once and it'll remember it. However, we have monthly channel updates enabled through GPO for Office 365 and the manual uncheck gets overridden every time Office pushes an update.
