The user needs to restore a dynamic workflow button that adds the next signature field, which disappeared after a signed PDF was manually attached to an email instead of being routed via the built-in email action.

How to Restore a PDF Signature Workflow After Emailing Manually
Product
PDF Editor
Device & OS
not provided
Scenario
Routing a PDF document through an approval workflow that requires multiple signatures.
Observed behavior
The interactive button to add the next signature field vanishes permanently once the document is signed and manually sent via an external email client.
Before you start

Before proceeding, check if you have a backup of the original, unsigned PDF form. Digital signatures often permanently lock form fields to prevent tampering, making it impossible to restore deleted buttons on the signed copy.

Solution 1Recommended

Revert to the Unsigned PDF Source Document

Use this method to recover the workflow functionality if the document is already signed and locked.

Applying a digital signature inherently locks the document's state to protect its integrity. Because of this security measure, dynamic workflow buttons cannot be recovered once they are removed from a locked file.

1
Locate the original file

Find the original, unsigned version of the PDF form in your local files or document management system.

2
Create a fresh copy

Duplicate the unsigned file to avoid overwriting your master template during the new workflow attempt.

3
Restart the workflow

Initiate the approval workflow from the new copy, ensuring all participants follow the correct built-in routing procedures.

Revert to the Unsigned PDF Source Document
Document State: Attempting to modify or force changes on a securely signed document will invalidate the existing signatures.

Frequently Asked Questions

Why did the 'add next signature' button disappear after I signed?

When a digital signature is applied, it often locks the document's form fields and interactive elements to ensure the file's integrity and prevent post-signature tampering.

Can I remove my digital signature to restore the workflow buttons?

If you are the person who just applied the signature and the document hasn't been closed, you might be able to clear your signature by right-clicking it and selecting 'Clear Signature'. Once the file is saved and closed, the action generally cannot be undone.

Does attaching a PDF to an email manually break its scripts?

Yes, saving a workflow-dependent PDF locally and manually attaching it to an email can detach it from automated routing scripts or connected enterprise systems that rely on built-in submission actions.
