Encrypt with Password no longer available for document
Hi all,
I work with sensitive information and regularly send documents containing CUI. I store the pdf on my computer, and then:
- fill it out,
- sign with digital certificate
- protect with password
- send via email for others to sign
Suddenly, the option to encrypt with password is greyed out. I received an error message when trying to encrypt with password. Doesn't matter if the document is filled out, or a new blank copy. It is says

It is not signed.
My question is, why did this suddenly change? Why can I not protect this document with a password any longer?
Thank you so much for your help!!
