Solution 1Recommended

Set Outlook as the Default Mail Client

Windows relies on default app settings to bridge communication between Acrobat and your email client. Ensuring Outlook is the default resolves most routing issues.

If Windows does not explicitly recognize Microsoft Outlook as the default email handler, Acrobat Pro will fail to trigger the email composition window or access the associated address book.

1
Open Windows Settings

Click the Start menu and select the Settings gear icon, or press Windows Key + I on your keyboard.

2
Navigate to Default Apps

Click on 'Apps' from the main settings menu, then select 'Default apps' from the left-hand sidebar.

3
Select Microsoft Outlook

Under the 'Email' section, click the current default application and select 'Outlook' from the list of available apps. Restart Acrobat and try sending the file again.

Set Outlook as the Default Mail Client
Check In-App Settings: Also open Acrobat Pro, go to Edit > Preferences > Email Accounts, and ensure Microsoft Outlook is set as the 'Default' email application within Acrobat.

Frequently Asked Questions

Why is Acrobat unable to access my Outlook address book?

This commonly occurs if the Acrobat COM Add-in is disabled within Outlook, if Outlook is not set as the default mail app in Windows, or if your Outlook mail profile has become corrupted.

Can my antivirus or firewall block Acrobat from sending emails?

Yes. Strict security software can intercept cross-application communication, classifying the interaction between Acrobat and Outlook as suspicious behavior. Check your antivirus settings to ensure Acrobat is a trusted application.

How do I check my Outlook Add-ins for the Acrobat integration?

Open Outlook, navigate to File > Options > Add-ins. At the bottom of the window, ensure 'COM Add-ins' is selected in the Manage dropdown and click 'Go'. Verify that the 'Acrobat PDFMaker Office COM Addin' is checked.
