Set Default Mail App and Repair Applications

Configuring Microsoft Outlook as your system's default email client and repairing both software installations usually restores the necessary integration components.

The communication between Acrobat Reader and Microsoft Outlook relies heavily on Windows default application settings and healthy registry keys. Updating these settings forces the applications to recognize each other.

1
Set Outlook as Default App

Open Windows Settings, navigate to Apps > Default apps. Locate the 'Email' section and select Microsoft Outlook as the default application.

2
Repair Acrobat Reader

Launch Adobe Acrobat Reader. Click on 'Help' in the top navigation menu and select 'Repair Installation'. Allow the process to complete and restart the application.

3
Update Microsoft Outlook

Open Microsoft Outlook, go to File > Office Account. Click on 'Update Options' and select 'Update Now' to ensure you have the latest patches.

4
Test the Email Integration

Open a PDF in Acrobat Reader and click the email icon. Select 'Default email application' to verify if Microsoft Outlook successfully launches with the PDF attached.

Acrobat Sign Add-in: If you are specifically trying to use the Adobe Acrobat Sign add-in for Outlook rather than the standard email attachment feature, you may need to consult Adobe's official add-in documentation to authenticate your account.

Frequently Asked Questions

Why does Acrobat Reader's email button work with webmail but not Outlook?

Webmail uses a simple browser-based link, whereas desktop Outlook requires specific Windows registry keys and MAPI (Messaging Application Programming Interface) configurations to communicate with external applications like Acrobat Reader.

Will reinstalling Acrobat Reader fix the email attachment issue?

Yes, completely uninstalling and then reinstalling Acrobat Reader can often repair corrupted registry files and restore the missing communication links between the PDF reader and your desktop email client.

How do I change the default email application inside Adobe Acrobat?

Open Acrobat Reader, navigate to Edit > Preferences > Email Accounts. From this menu, you can add a new account, choose a webmail service, or designate a specific desktop email application as your default choice.
