Fix PDF Form Email Button Not Working in Acrobat Reader
Question details
The email submission button on a PDF form functions correctly in Adobe Acrobat Pro but becomes unresponsive or fails when opened by end-users in Adobe Acrobat Reader.

- Product
- Adobe Acrobat Pro and Reader
- Device & OS
- not provided
- Scenario
- Distributing a fillable PDF form that requires users to submit their completed data automatically via an embedded email button.
- Observed behavior
- The email button triggers the email client properly in Acrobat Pro, but fails to execute the submit action when the saved form is opened and used in the free Adobe Acrobat Reader.
Ensure you are editing the original PDF form in Acrobat Pro, and verify that your default desktop email client (such as Outlook or Apple Mail) is correctly configured to handle 'mailto' requests.
Enable Reader Extended Features for Form Fill-in
Adobe Reader requires specific usage rights applied by Acrobat Pro so that free users can save and submit form data.
By default, Adobe Acrobat Reader restricts users from saving filled form data or executing certain submit actions. To resolve this, the creator must grant extended privileges to the document before distributing it.
Launch Adobe Acrobat Pro and open your finalized, fillable PDF form.
Navigate to the 'File' menu in the top toolbar, select 'Save As Other', and then choose 'Reader Extended PDF'.
Select 'Enable More Tools (includes form fill-in & save)' from the fly-out menu. A prompt will appear explaining the rights being applied.
Click 'Save Now' and save this version as a new file. Distribute this newly saved file to your Adobe Reader users.

Reconfigure the Button's Submit Action
An incorrectly formatted 'mailto' address or unsupported submit action type will cause the email button to fail silently.
Fill and Share PDF Forms Easily with WPS Office
Skip complicated usage rights and permissions settings. WPS PDF provides an intuitive way to fill out PDF forms, save your data locally, and share the document directly without needing expensive software.
- 1. Open the form in WPS PDF: Launch WPS Office and open your fillable PDF document.
- 2. Fill out the fields: Click on the interactive text boxes, dropdowns, or checkboxes to easily input your information.
- 3. Save your progress: Press Ctrl+S or click 'File' > 'Save' to retain all your entered data without any restricted permission errors.
- 4. Share via email: Click the 'Share' or 'Email' icon in the top toolbar to automatically attach the completed PDF to your default email application.

Frequently Asked Questions
Why does the submit button work on my PC but not for the people I send it to?
If you created the form in Acrobat Pro, it works on your machine because you inherently have full editing rights. Users opening it in the free Adobe Reader lack these permissions unless you explicitly save the document with 'Reader Extended' rights enabled.
Can I use an 'Open a web link' action instead of 'Submit a form' for the email button?
While you can use an 'Open a web link' action with a mailto URL, this method will only open a blank email draft. To successfully attach the filled form data or the PDF itself to the email, you must use the 'Submit a form' action.
Why does nothing happen when I click the email button in Adobe Reader?
This usually happens for three reasons: the document lacks Reader Extended usage rights, the 'mailto:' URL is formatted incorrectly, or the user's computer does not have a default desktop email client (like Outlook or Windows Mail) configured to catch the request.
