The user needs to understand why Adobe Acrobat automatically dispatched an email containing sensitive personal data and how to prevent it and handle the breach.

Stop Adobe Acrobat from Automatically Sending Emails with Sensitive Information

Product: Adobe Acrobat
Device & OS: not provided
Scenario: Submitting a reply or form within an Acrobat document that contains attached or embedded personal details.
Observed behavior: An email was automatically generated and sent upon submitting a reply in Acrobat, exposing sensitive data from an attached online book (including delivery address, phone number, and Aadhaar number) without explicit user confirmation.

Before you start

Immediately disconnect your device from the internet or force-close your email client to stop any pending automated emails in your outbox, and avoid sharing any further documents until you have secured your privacy settings.

Solution 1Recommended

Revoke Document Access and Adjust Notification Settings

Immediately restrict access to the shared document and disable automated review or reply notifications in Acrobat to prevent further data exposure.

When Acrobat is configured for Shared Reviews or specific automated workflows, it may automatically trigger emails when comments or forms are submitted. Your first priority is mitigating the data leak before fixing the software settings.

Revoke Document Access

Open Adobe Acrobat, navigate to the 'Shared by You' section under the Home tab, select the compromised document, and choose 'Unshare' or manually remove individual recipients to block further access.

Notify Affected Parties

Urgently contact the recipients who received the automated email and request that they permanently delete the email and any downloaded attachments.

Modify Tracker Settings

In Acrobat, go to 'Edit' > 'Preferences' > 'Tracker' (or 'Reviewing') and disable automatic email notifications for comments, replies, or form submissions.

Check Workflows and Action Wizard

Navigate to 'Tools' > 'Action Wizard' and ensure there are no active automated scripts or actions that trigger emails upon document submission.

Revoke Document Access and Adjust Notification Settings

Contact Security Teams: If highly sensitive data like an Aadhaar number was exposed, report the incident to your organization's privacy and security team immediately for compliance and further guidance.

Solution 2

Redact and Sanitize PDFs Before Sharing

Permanently remove visible sensitive information, hidden metadata, and attachments before initiating any review or sharing process.

Frequently Asked Questions

Why did Adobe Acrobat send an email without asking me?

Acrobat may automatically send emails if it is part of a Shared Review, connected to a SharePoint/Office 365 workflow, or if an embedded script or Action triggers an email upon submitting a form or reply.

Can I unsend the automated email sent by Acrobat?

Once the email is dispatched through your email client or Adobe's servers, it cannot be traditionally 'unsent'. However, you can immediately unshare the document via the Adobe Document Cloud to revoke access to the file itself.

How do I remove attached files from a PDF?

Open the attachments panel in your PDF reader (usually represented by a paperclip icon on the left sidebar), select the attached file containing the sensitive information, and press the Delete key. Save the document to apply the changes.

Is redacting a PDF safer than just drawing a black box over the text?

Yes. Drawing a black shape over text only covers it visually; the underlying text can still be highlighted, copied, or read by screen readers. Proper redaction permanently deletes the text data from the file's underlying code.
