How to Fix Acrobat Cannot Send PDF Attachments via Custom Email Server
Question details
The user is unable to send PDF attachments directly from Adobe Acrobat DC through a custom GoDaddy email account configured in Outlook, resulting in a server communication error.

- Product
- Adobe Acrobat DC, Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Attempting to email a PDF directly from Acrobat using a custom domain email server in Outlook.
- Observed behavior
- Acrobat returns an error communicating with the server for the custom email account, despite working correctly for Gmail and standard Microsoft accounts.
Before troubleshooting Acrobat's email integration, verify that you can send regular emails directly from Microsoft Outlook using the custom GoDaddy email account to ensure the server is online and functioning.
Verify Default Email Client and SMTP Settings
Ensure Outlook is set as the default email client and your SMTP settings are accurately configured for your custom domain to allow Acrobat to communicate with it.
Acrobat relies heavily on the default system configurations to push attachments to Outlook. If multiple accounts are added or authentication protocols have changed, Acrobat may fail to execute the send command.
Open your computer's 'Default apps' settings from the Windows Start menu and ensure Microsoft Outlook is set as the default email client.
In Outlook, navigate to File > Account Settings > Account Settings, and select your custom GoDaddy email account.
Click 'Repair' or 'Change' to verify that the outgoing mail server (SMTP) details match your email provider's current requirements, including the correct port numbers and SSL/TLS encryption methods.

Manually Attach the PDF in Outlook
Bypass Acrobat's built-in email integration by manually attaching the saved PDF document directly in a new Outlook message.
Switch to a Supported Webmail Account in Acrobat
Use a standard webmail account like Gmail or Outlook.com that is natively supported by Acrobat's share feature.
Edit and Email PDFs Seamlessly with WPS Office
Avoid complex server communication errors with a lightweight, all-in-one PDF solution. WPS Office allows you to edit, comment, and quickly share PDF documents through your system's default email client without complicated server configurations.
- 1. Open the PDF in WPS: Launch WPS Office and open the PDF document you wish to send.
- 2. Access the Share Menu: Click on the 'Menu' button in the top left corner and navigate to 'Share' or select the 'Email' icon from the toolbar.
- 3. Launch Default Client: WPS Office will automatically open your default email client (such as Outlook) with the PDF securely attached to a new draft.
- 4. Send the Document: Enter the recipient's email address and click send, bypassing complex in-app SMTP setups.

Frequently Asked Questions
Why does Acrobat fail to communicate with my custom email server?
Acrobat's built-in email protocol may struggle with custom domains (like GoDaddy) that require strict or non-standard SMTP authentication, especially if multiple accounts with different protocols are active simultaneously in Outlook.
Can I use webmail like Gmail directly inside Acrobat instead of Outlook?
Yes, Acrobat natively supports linking webmail accounts such as Gmail and Outlook.com. You can configure this by choosing 'Add Webmail' from the email share prompt, which bypasses Outlook entirely.
How do I update Acrobat to ensure email integration works?
Open Adobe Acrobat, navigate to Help > Check for Updates, and install any available patches. Adobe frequently releases updates that fix compatibility and communication errors with third-party email clients.
