- Product
- Adobe Acrobat X Pro
- Device & OS
- not provided
- Scenario
- Trying to submit a completed and signed PDF form using the Save and Send functionality.
- Observed behavior
- The form successfully accepts the electronic signature, but an error message appears when using Save and Send to submit the document.
Ensure you have editing or administrative privileges for the original, unsigned PDF form so you can modify its saving permissions.
Enable Additional Features for Reader Extended PDF
By enabling extended PDF features, you grant standard Adobe Reader users the permission to save form data, preventing submission errors.
This error generally occurs because the PDF form has not been authorized to allow standard Adobe Reader users to save form data. By resaving the file with extended features enabled, you remove this restriction and allow seamless submission.
Open your PDF form in Acrobat X Pro. Go to the top menu bar, click on 'File', and hover over the 'Save As' option.
From the 'Save As' submenu, select 'Reader Extended PDF' and then click on 'Enable Additional Features'.
Save the modified PDF file to your computer and completely close the document.
Reopen the newly saved PDF, apply the signature if necessary, and use the Save and Send feature again to submit your form.

Frequently Asked Questions
Why does Adobe Acrobat show an error when sending a signed PDF?
This usually happens because the form lacks the necessary extended permissions that allow users to save filled form data locally. Enabling 'Reader Extended PDF' features resolves this restriction.
Will enabling extended features remove existing signatures?
Yes, modifying the document's security or extended features can invalidate or remove existing digital signatures. It is required to apply the 'Enable Additional Features' setting to the blank form before any users fill and sign it.
Can I enable Reader Extended PDF features in the free Adobe Reader?
No, you need Adobe Acrobat Pro or Acrobat Standard to apply these extended permissions to a PDF file. The free Adobe Reader can only utilize these saving features once they are enabled by the document author.
