Edit the Submit Button Properties in Adobe Acrobat
Access the form editing mode to modify the action associated with your submit button, allowing you to delete or correct the broken email address.
PDF form submit buttons are often programmed to send filled data to a specific email address using a "mailto:" command. When this address is mistyped or no longer valid, Acrobat will throw an "Invalid server" error. Editing the button's properties will resolve this issue.
Open your PDF form in Adobe Acrobat. On the top menu or right-hand pane, navigate to "Tools", select "Form", and then click on "Edit" to enter the form modification interface.
Locate the Submit button on the document. Right-click the button and select "Properties" from the context menu.
In the Properties dialog box, switch to the "Action" tab. Review the configured script or "Submit a form" action to find the email address. Highlight the action and click "Edit" to correct the email address, or click "Delete" to completely remove the email submission requirement.
Click "Close" on the Properties window. Exit the form editing mode, save your PDF document, and click the Submit button again to verify that the error has been cleared.
