How to Fix Acrobat XI PDF Form Submit Button Not Sending Email
Question details
The JavaScript mailDoc submit button fails to generate an email in Acrobat XI after selecting an email client, despite working correctly in newer versions like Acrobat Pro DC.

- Product
- Adobe Acrobat XI
- Device & OS
- not provided
- Scenario
- A user is trying to submit an interactive PDF form via email using a built-in JavaScript mailDoc button.
- Observed behavior
- The submit button does nothing after the email client is selected, failing to open a new email draft or send the PDF form.
Ensure you have a default desktop email client (such as Microsoft Outlook or Mozilla Thunderbird) installed and properly configured, as the PDF mail mechanism relies on local applications rather than browser-based webmail.
Verify Default Email Client and OS Integration
Ensure your operating system properly recognizes your desktop email client to allow Acrobat XI to hand off the email generation process.
Acrobat relies heavily on the operating system's MAPI (Messaging Application Programming Interface) to communicate with your email software. If the OS integration is broken or the default app is unassigned, the JavaScript action will silently fail.
Navigate to your computer's system settings and open the 'Default Apps' or 'Default Programs' menu.
Locate the 'Email' section and select your preferred desktop mail client (e.g., Outlook) as the default application.
Restart Adobe Acrobat XI, open your PDF form, and click the submit button again to verify if the email draft is generated.

Check Acrobat JavaScript and Security Preferences
Adjust your Acrobat XI security settings to ensure that JavaScript execution is not being blocked.
Test with a Basic mailDoc Script
Isolate the issue by testing a simple JavaScript command to confirm if the problem lies with the code or the environment.
Fill and Share PDF Forms Easily with WPS Office
If older software like Acrobat XI fails to integrate with modern operating systems, you can seamlessly open, fill out, and email your PDF forms using WPS Office's built-in PDF tools.
- 1. Install the software: Download and install the free version of WPS Office on your computer.
- 2. Open your PDF form: Launch WPS PDF and open your interactive PDF form.
- 3. Fill the form: Click on the form fields to directly input your required information.
- 4. Share via email: Click the 'Share' or 'Email' icon in the top toolbar to automatically attach the completed form to a new message in your default desktop email client.

Frequently Asked Questions
Why does the mailDoc JavaScript work in Acrobat DC but not Acrobat XI?
Acrobat DC is actively updated to maintain compatibility with modern operating systems and their email APIs. Acrobat XI is an older, unsupported version that often fails to communicate properly with the latest Windows or macOS email routing systems.
Do I need a desktop email client to use the PDF submit button?
Yes, the PDF mailDoc function typically requires a locally installed desktop email client (such as Microsoft Outlook or Apple Mail) configured with MAPI. It cannot automatically send emails through web-based services like Gmail or Yahoo in a browser.
Will upgrading my Acrobat software fix the submit button issue permanently?
Yes, upgrading from the unsupported Acrobat XI release to a current version like Acrobat DC, or switching to a modern alternative like WPS Office, is the safest long-term solution to ensure seamless OS integration and security.
