Device & OS
not provided
Scenario
Attempting to share or send a PDF file using the built-in email feature in Adobe Acrobat.
Observed behavior
The email function fails to open the mail client or attach the document, preventing the user from sending the PDF directly from the application.
Before you start

Ensure that you have a default desktop email client (such as Microsoft Outlook, Apple Mail, or Windows Mail) installed, fully updated, and correctly logged in on your computer.

Solution 1Recommended

Verify and Set Your Default Email Application

Acrobat relies on your operating system's default email client to draft messages. Ensuring this is configured correctly is the most common and effective fix.

If your system does not have a designated default email application, Acrobat will not know where to send the document data, resulting in an error or no response.

1
Open System Settings

On Windows, press the Windows key + I to open Settings, then navigate to 'Apps' and select 'Default apps'.

2
Set Default Mail Client

Click on the 'Email' section and choose your preferred installed email application, such as Outlook.

3
Configure Acrobat Preferences

Open Adobe Acrobat, go to 'Edit' > 'Preferences' > 'Email Accounts'. Ensure your default email client is listed and set as the default within Acrobat.

Verify and Set Your Default Email Application
Webmail Option: If you don't use a desktop mail client, you can add a webmail account (like Gmail) directly in Acrobat's 'Email Accounts' preferences.

Frequently Asked Questions

Why is my default email application not recognized by Acrobat?

Acrobat might lose connection with the system's default app settings after a major OS update or application upgrade. Re-setting the default mail app in your Windows or Mac system settings usually re-establishes this connection.

Does webmail work with Acrobat's 'Send by Email' feature?

Yes, Adobe Acrobat allows you to configure webmail accounts like Gmail, Yahoo, or Outlook.com. You need to add the account via Acrobat's Preferences under the 'Email Accounts' section and authorize the connection.

Can a firewall or antivirus block Acrobat from sending emails?

Yes, overly strict firewall rules or antivirus settings can block Acrobat from communicating with your desktop email client or webmail servers. Adding Adobe Acrobat to your security software's whitelist or allowed apps can resolve this issue.
