How to Fix Gmail Draft Error When Sending a Signed PDF in Adobe Acrobat

Product: Adobe Acrobat Reader DC
Device & OS: not provided
Scenario: Sending a digitally signed PDF document via email using Adobe Acrobat's Gmail integration.
Observed behavior: Adobe opens Gmail as a draft, but Gmail immediately reports that the conversation does not exist, preventing the email from being sent successfully.

Before you start

Ensure you have a stable internet connection and have saved a local copy of your signed PDF to prevent any data loss while adjusting your email settings.

Solution 1Recommended

Re-link Your Gmail Account in Adobe Acrobat Preferences

Removing and re-adding your Gmail account refreshes the connection permissions, which typically resolves draft synchronization errors.

This error generally occurs because the authentication token between Adobe Acrobat and Gmail has expired or encountered a permissions glitch. Re-establishing the connection forces Acrobat to request fresh permissions.

Open Preferences

Open Adobe Acrobat Reader DC, click on 'Edit' in the top menu bar, and select 'Preferences' from the dropdown menu.

Remove the Existing Gmail Account

Select 'Email Accounts' from the categories on the left side. Click on your linked Gmail account in the list, then click the 'Remove' button.

Add the Account Again

Click 'Add Account', select Gmail, and follow the on-screen prompts to sign in and grant Adobe Acrobat permission to connect to your Gmail account.

Retry Sending the PDF

Open your signed PDF document and try using the Send and Track feature again to verify that the draft error is resolved.

Re-link Your Gmail Account in Adobe Acrobat Preferences

Permission Check: Make sure you allow all requested permissions when signing into Google; otherwise, the draft creation process will continue to fail.

Solution 2

Manually Attach the Signed PDF in Gmail

If the built-in integration continues to fail, you can bypass Adobe's email feature and send the document directly through your web browser.

Frequently Asked Questions

Why does Gmail say 'the conversation does not exist' when using Adobe Acrobat?

This usually happens when the authentication token between Adobe Acrobat and Gmail expires or becomes corrupted. Re-linking the account forces a new, valid connection.

Does removing my Gmail account from Adobe Acrobat delete my emails?

No, removing the account from Acrobat's preferences only revokes the application's shortcut to send emails on your behalf. Your actual Gmail account and its contents remain completely safe and untouched.

Can I use a different email provider with Adobe Send and Track?

Yes, Adobe Acrobat supports adding standard email accounts, including Outlook, Yahoo, or any other provider via IMAP/SMTP in the Email Accounts preferences.

Are digital signatures preserved when I attach the PDF manually?

Yes, as long as you save the document after applying your digital signature, the signature data is embedded directly into the PDF file and will be preserved regardless of how you email it.
