Disable prompt on opening attachments

[Jurgen Wildhagen]

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

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.

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

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!

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.

 

Best regards,

Hello @AllainU,

Are you able to guide me with the instructions to turn this off within Nitro Pro, please. Version 13.35.3.685. Thanks in advance!

Hello @Ron Echon,

Thank you for reaching out to us through our Community Forums!

You can disable this feature through Outlook, however you will need to run MS Outlook as an Administrator for this affected user. Please follow the steps outlined below to turn this prompt off:

1. Close MS Outlook
2. Hold CTRL + SHIFT buttons while clicking on your Outlook icon, then select 'Run As Administrator'
3. Accept the User Account Control (UAC) security prompt and provide Administrator credentials if asked to
4. Open the attachment and un-check the 'Always ask before opening this type of file' box.
5. Close Outlook and start it as a normal user.

Your changes will be saved going forward and you should not be prompted by this warning again.

If above steps did not help, another work-around is by going to the registry and to HKEY_CLASSES_ROOT\.pdf and forcing it to "AcroExch.Document".

Thank you for choosing Nitro and I hope this helps.
