How to Fix Adobe Send for Signature Error in PDF Documents

Product: Adobe PDF Pack
Device & OS: not provided
Scenario: Attempting to send a PDF document to recipients for an electronic signature.
Observed behavior: The application fails to process the request, aborts the send action, and displays an unspecific error message.

Before you start

Make sure your internet connection is stable and take note of the exact error code or text displayed before proceeding with troubleshooting.

Solution 1Recommended

Test with an Alternative PDF Document

Determine whether the issue is caused by a corrupted file, specific document restrictions, or a broader application failure.

Often, signature errors are isolated to a single file that may have hidden security restrictions or corrupted metadata. Testing with a clean, blank PDF helps pinpoint the root cause.

Create a new document

Create a completely blank PDF or a simple text document and save it as a new PDF file.

Initiate the signature process

Open the new PDF in your application and select the Send for Signature tool.

Send a test request

Attempt to send the document for signature to your own alternate email address.

Evaluate the result

If the test document sends successfully, the original file is likely corrupted or restricted. If the error persists, the issue lies within the software or account authentication.

File Restrictions: Check the original document's properties to ensure it doesn't already contain a certifying digital signature, which can block subsequent signature requests.

Solution 2

Re-authenticate Your Cloud Services Account

Resolve background synchronization or session timeout errors that prevent the signature service from connecting to cloud servers.

Frequently Asked Questions

Why does my PDF say it cannot be sent for signature?

This commonly occurs if the PDF file is protected with a password, contains previously certified digital signatures, or has restricted editing permissions. Check the Document Properties under the Security tab to ensure no restrictions are blocking the process.

How do I fix a network error during the Send for Signature process?

Ensure your internet connection is active. Sometimes, overly strict firewalls or antivirus software block cloud servers. Try temporarily disabling your firewall or whitelisting the software's domains in your network settings.

Does WPS Office support electronic PDF signatures?

Yes, WPS Office includes a robust PDF editor that allows you to easily draw, type, or upload an image of your signature. You can apply it directly to your PDF documents and save or share them instantly.
