"Save a Copy" is only available in Acrobat. Adobe Reader users can save extended PDF files after comments or form fields have been applied but can't turn off the extended rights by doing so.
It's not possible to disable the Save a Copy menu item in Adobe Acrobat by use of any scripts or security settings within the PDF file.
Thanks - I feared so
Our whole enterprise of tens of thousands of users has Acrobat Pro installed on desktops, laptops etc.
Failure rate due to losing saving rights is only about 5% max with good instructions. That's not too bad given max limit of collected forms is 500 . . .
Do they really need to save the form? They can always be set to print, but the save is not needed to submit data. That simplifies the process and eliminates the 500 limit issue. When you get the data file, simply import it to the form (1 extra step - and in some cases it will actually open the form and fill it in).
I should have been clearer, but my understanding was that to submit using the "submit" button, users need to be using an email client. Our organisation has almost no users using an email client as we connect via webmail. This is why I need to tell users to complete and save the form and email ack to me as an attachment.
Does this make sense?
