Fix Adobe Acrobat Mobile Submit Function Not Working on iOS
Question details
The user is unable to submit a filled PDF form via email using the app's Submit button.

- Product
- Adobe Acrobat Mobile
- Device & OS
- iOS
- Scenario
- Attempting to submit a PDF form directly from the Adobe Acrobat Mobile app after updating to version 22.12.
- Observed behavior
- The app displays an error stating 'Email has not been set up on this device', even though the email is properly configured and worked in the previous 22.11 version.
Ensure that the native Apple Mail app on your iOS device is set up with an active email account, as mobile PDF readers typically rely on the default system mail client to process form submissions.
Verify iOS Default Mail Settings and Update the App
Checking your native iOS Mail app configuration and installing the latest Acrobat patches can resolve communication errors between the PDF app and the device's mail system.
Starting with certain updates, Adobe Acrobat Mobile strictly requires the native Apple Mail app to trigger the 'mailto:' action embedded in PDF submit buttons. If you only use third-party apps like Gmail or Outlook, the submission might fail.
Go to your iPhone or iPad Settings, scroll down to Mail, tap on 'Default Mail App', and ensure it is set to the native iOS Mail app.
Open the native Apple Mail app and verify that your email account is actively logged in, syncing, and capable of sending out emails.
Open the App Store, search for Adobe Acrobat, and tap 'Update' to install any newer versions beyond 22.12 that may contain bug fixes for the submit function.

Manually Share the Filled PDF Form
If the embedded submit button continues to fail, manually attaching the saved PDF to an email is a reliable workaround.
Use WPS Office for Seamless PDF Form Filling on iOS
If your current PDF reader continues to experience form submission errors on your iPhone or iPad, switch to WPS Office. It provides a stable, lightweight, and highly compatible environment for reading, filling, and sharing PDF forms directly from your mobile device.
- 1. Install the App: Download WPS Office for free from the App Store on your iOS device.
- 2. Open the PDF: Launch WPS Office and open your interactive PDF form to fill in your information.
- 3. Share the Document: Tap the Share button to easily send the completed PDF form via your preferred email or messaging app.

Frequently Asked Questions
Why does Acrobat say 'Email has not been set up' when I have the Gmail app installed?
Adobe Acrobat Mobile and many other iOS apps rely on the native Apple Mail app to execute automated email commands (like a PDF Submit button). If your email is only set up in a third-party app like Gmail and not linked to the native iOS Mail settings, the app cannot detect an active email configuration.
Can a poorly formatted PDF form cause the submit button to fail on mobile?
Yes. If the creator of the PDF form used complex JavaScript or an outdated submit command, mobile PDF readers might fail to process it. Testing a different PDF form can help determine if the issue is with the app or the specific file.
How can I check which app was used to create the PDF form?
You can open the PDF document properties to find out how it was created. In Adobe Acrobat, tap the three-dot menu, select 'Properties' or 'Document Information', and look at the 'Application' or 'PDF Producer' fields to see the origin of the file.
