When attempting to password protect a PDF, I get the message "You cannot change security on this document because this document is signed or certified." Is there any way to do this (password protecting) with a signed, certified PDF? (Adobe Acrobat Standard 2017)
No. It needs to be done before the file is signed.

Thanks, was thinking that what the issue was. The PDF came to the user signed and was attempting to put a password on it.
