How to Fix PDF Submit Buttons That Only Work in Preview Mode

Device & OS

Scenario
Distributing a fillable PDF form that requires users to click a button to submit their data via email or a server.
Observed behavior
The Submit button triggers the expected action in preview mode but fails to work in actual usage environments like web browsers or Reader Touch.
Before you start

Ensure your computer has a default desktop email client (like Outlook or Windows Mail) properly configured, as PDF email submission buttons rely on the system's default mail application to function.

Solution 1Recommended

Correct the "mailto:" Link Formatting in Button Properties

A common cause for submit button failures is incorrect capitalization or errant spacing in the email hyperlink structure.

If your form uses an email submission action, the target URL is highly sensitive to syntax. Any deviation from standard formatting will cause the button to fail in live environments even if it seems to work in preview.

1
Access Button Properties

Open your PDF form in edit mode, right-click the malfunctioning Submit button, and select Properties from the context menu.

2
Edit the Submit Action

Navigate to the Actions tab, locate the "Submit a form" action in the list, and click the Edit button.

3
Fix the Target URL Format

Verify that the submission URL begins exactly with 'mailto:' in all lowercase letters, immediately followed by the email address with no spaces (e.g., use 'mailto:forms@example.com', not 'Mailto: forms@example.com').

4
Save and Test

Click OK to save the action, exit form editing mode, save the document, and test the button.

Frequently Asked Questions

Why does my PDF submit button do nothing when opened in Chrome or Edge?

Most web browsers use native, simplified PDF viewers that do not support interactive form scripts or `mailto:` submission actions. Users must download the file and open it in a dedicated desktop PDF reader to use these features.

Do users need an email client installed to use an email submit button?

Yes. If the PDF submit button is configured using a `mailto:` link, the user must have a desktop email client (such as Outlook, Apple Mail, or Thunderbird) configured as their system's default mail app to generate the outgoing message.

How can I safely test if my PDF submit button is working?

After saving your edited PDF, close your PDF editor completely. Reopen the file in a standard desktop PDF reader, fill out some test data, and click the Submit button. A draft email should automatically open in your default email application with the form data attached.
