Device & OS
not provided
Scenario
Sharing or emailing a filled PDF form to recipients directly from the PDF application.
Observed behavior
The PDF software defaults to the system's primary email application or browser account, preventing the user from sending the document from their preferred enterprise address.
Before you start

Ensure you have the login credentials for the specific email address you wish to use, and verify that it is properly added to your device's mail application.

Solution 1Recommended

Configure the Default Email Account in Your System's Mail Client

Change the default sending address within the email application that your PDF reader opens automatically.

Most PDF applications cannot override the default sender configured by your operating system or email service. To fix this, you must change the default account settings directly within the mail application that launches when you click send.

1
Identify the default mail app

Click the email option in your PDF software and note which application (e.g., Outlook, Apple Mail, or a browser) automatically opens.

2
Open account settings

Navigate to the settings or preferences menu of that specific email application.

3
Set the default sender address

Locate the default account settings and select your preferred enterprise or company email address as the default for sending new messages.

4
Verify and send

Return to your PDF application, select the email option again, and verify that the outgoing message now uses the correct sender address.

Configure the Default Email Account in Your System's Mail Client
System Permissions: Make sure your enterprise address is authorized to send messages on that device, otherwise the email may fail to send.

Frequently Asked Questions

Why does my PDF software open the wrong email account?

PDF applications rely on your operating system's default mail client and its configured primary account. They cannot override these system-level settings automatically, which is why the default personal account might open instead of your company address.

Can I set up a webmail account like Gmail as the default for PDF sharing?

Yes, you can set a web browser or a specific webmail wrapper application as your default mail client in your operating system's settings. Once set, your PDF software will route sharing requests through that webmail interface.

Does changing the sender email address affect my digital signature?

No, changing the email address you use to send the document does not invalidate or alter the digital or electronic signature applied during the Fill & Sign process.
