Question details
The user needs to fix the Acrobat Reader feature that allows sending PDFs via email, which currently fails to integrate with the Outlook desktop app.

- Product
- Adobe Acrobat Reader, Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Attempting to share a PDF document as an email attachment directly from the PDF viewer using a desktop email client.
- Observed behavior
- The "Attach to Email" command works successfully with webmail services but does not launch or respond when attempting to use Microsoft Outlook.
Ensure that your Microsoft Outlook application is fully updated, an active email profile is configured, and any unsaved work in your PDF document is saved before starting the troubleshooting process.
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.
Open Windows Settings, navigate to Apps > Default apps. Locate the 'Email' section and select Microsoft Outlook as the default application.
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.
Open Microsoft Outlook, go to File > Office Account. Click on 'Update Options' and select 'Update Now' to ensure you have the latest patches.
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.
Easily Attach and Send PDFs using WPS PDF
If integration issues persist between other applications, WPS PDF offers a built-in, hassle-free way to view, edit, and email your PDF documents directly from the application without complex add-in configurations.
- 1. Open Your PDF in WPS Office: Download and install WPS Office. Launch WPS PDF and open the document you wish to share.
- 2. Access the Share Menu: Navigate to the top toolbar and click on the 'Share' or 'Menu' button.
- 3. Select Email: Choose the 'Email' option from the dropdown list to trigger your default email client.
- 4. Send the Attachment: A new email draft will automatically open in your default mail app with the PDF seamlessly attached and ready to send.

Frequently Asked Questions

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.
