Message save a blank message of this form - How to Avoid this message.

hello,

we are getting this message if we try to save a signed document (via adobe Sign or by using Fill & Sign in Adobe Reader.

How can we avoid this message? (like vie GPO or Registry Settings).

The problem only happens by saving "signed" documents.

We have over 20.000 users, and i dont want to explain each user to check the checkbox.

Please support.

Thank you.
