Hi, I had to set-up a digital signature to enable me to sign a form in PDF format. Now every PDF I email is digitally signed, even if it has not been created in Acrobat. This causes a problem for the recipient. I have tried to delete the certificate in Acrobat under preferences and also in keychain access on the Mac, but without success. The system I am using is Mac OS 10.11.4, Acrobat Pro DC.
How exactly do you email? I wonder if something outside Acrobat is signing it.
