Fix Acrobat XI Cannot Send Email Through 64-Bit Outlook 2013
Question details
The user is unable to send PDF files directly from Acrobat XI using 64-bit Outlook 2013 due to a default mail client or MAPI error.

- Product
- Acrobat XI, Microsoft Outlook 2013
- Device & OS
- Windows
- Scenario
- Attempting to use the built-in email feature in Acrobat XI to attach and send a PDF via 64-bit Outlook 2013.
- Observed behavior
- Acrobat XI displays an error stating there is no default mail client or a MAPI error, despite Outlook 2013 being properly configured as the default email application.
Ensure that your Windows operating system has all the latest updates installed and that Outlook 2013 is successfully sending and receiving emails normally before modifying any MAPI settings.
Install Latest Compatibility Updates and Repair MAPI
Applying the latest patches for both Acrobat XI and Office 2013 can sometimes patch the broken MAPI communication between the 32-bit and 64-bit architectures.
Acrobat XI was designed primarily around 32-bit architecture. When it attempts to call the 64-bit MAPI subsystem in Outlook 2013, the request often fails. Ensuring both applications are fully updated is the first step to resolving the conflict.
Open Acrobat XI, click on the 'Help' menu at the top, and select 'Check for Updates'. Follow the prompts to install any available patches.
Open Microsoft Word or Outlook 2013, go to 'File' > 'Office Account', click on 'Update Options', and select 'Update Now'.
Open the Windows Control Panel, go to 'Programs and Features', right-click on your Microsoft Office 2013 installation, select 'Change', and then run a 'Quick Repair' or 'Online Repair'.
Switch to the 32-Bit Version of Outlook 2013
Uninstalling the 64-bit version of Office and installing the 32-bit version ensures native compatibility with older 32-bit applications like Acrobat XI.
Use Webmail or Manual Attachment
Bypass the local MAPI integration entirely by manually attaching the PDF to an email, or by configuring Acrobat to use a webmail service.

Frequently Asked Questions
Why does Acrobat XI show a MAPI error with 64-bit Outlook?
Acrobat XI is a 32-bit application. When it tries to trigger an email, it looks for a 32-bit MAPI component. Because 64-bit Outlook uses a 64-bit MAPI subsystem, Acrobat cannot communicate with it, resulting in a default mail client error.
Can I keep 64-bit Office and still fix this issue?
Sometimes installing the very latest patches for both programs can resolve it, but if the architectural mismatch persists, you will need to either downgrade Office to 32-bit, upgrade your Acrobat version, or attach the PDF manually.
How do I check if my Outlook 2013 is 32-bit or 64-bit?
Open Outlook 2013, click on 'File' > 'Office Account' > 'About Outlook'. The window that appears will display the version number followed by either '32-bit' or '64-bit'.
