Confirm Security Prompt When Printing PDF from Outlook

Ever since we installed the latest Adobe update yesterday we are getting an annoying security warning "Are you sure that this file is from a trustworthy source and you want to convert it?" every time you print to PDF from Outlook.

It doesn't seem to happen when you use the Outlook add-in for whatever reason. However, our users mostly print to PDF and this is very annoying for them.

We are running the latest version of Acrobat DC 2017 (2017.011.30138) along with Office 365 ProPlus software. This is on a Server 2016/2019 RDS environment.

Does anyone know how to disable this? It never happened until the Adobe update ran.

Hi,

I was having the same problem when trying to print to PDF out of Adobe InDesign. I think I may have found a fix. Here is what I did:

Open Adobe Acrobat Distiller DC

Go to File - Preferences

In the preferences window, check the very last checkbox (which says "Trust all files opened via Acrobat Distiller").

I did this and the dialog seems to have gone away.

    My version of Distiller does not show the "Trust all files opened via Acrobat Distiller" option.  I'm running version 19.10.20091315611 of Adobe Acrobat. Attached is a screenshot of what I see.

      I am having the same issue and mine, also, does not have that "Trust all files opened via Acrobat Distiller" check box.  Hoping someone has a solution.  Even this page didn't help.  How to disable the security warning message before postscript to PDF file conversion.  Basically the same fix for 2017 and 2015 but along with not having teh ckeck box in the Distiller preferences, I don't have the registry keys it mentions either.  Windows RDS server 2012 R2.
