Fix Suggested Outlook Contacts Not Appearing When Emailing a PDF from Acrobat
Question details
The user is unable to see suggested Outlook contacts when attempting to email a PDF directly using the Email button in Adobe Acrobat Pro DC.
- Product
- Outlook 2010 / Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Emailing a PDF file directly from Adobe Acrobat using the integrated Email button.
- Observed behavior
- Suggested contacts (auto-complete) work normally in Outlook but fail to appear in the email draft created by Acrobat.
Ensure you have saved any open PDF files and completely closed both Adobe Acrobat and Microsoft Outlook before performing these troubleshooting steps.
Verify Default Mail Client and Restart Applications
Setting Outlook as the default email client and restarting the applications often restores the MAPI integration.
Acrobat relies on the operating system's default mail settings to communicate with Outlook. If the default app mapping gets disrupted by a recent system update, the contact suggestion feature may stop working.
Close Adobe Acrobat Pro DC and Microsoft Outlook completely. Reopen both applications to see if the connection is refreshed and restored.
Open Windows Settings, navigate to Apps, and select Default apps. Look under the 'Email' section and ensure Microsoft Outlook is actively selected as your default mail client.
Open a PDF document in Acrobat Pro DC, click the Email button to draft a new message, and begin typing a contact name in the 'To' field to verify if suggestions now appear.
Repair Office Installation and Update Acrobat
Corrupted Office integration files or outdated Acrobat versions can break the auto-complete connection.
Review Security Software and Add-ins
Third-party security software or conflicting Outlook add-ins might block Acrobat from accessing the Outlook address book cache.

Frequently Asked Questions
Why does auto-complete work in Outlook but not when emailing from Acrobat?
When you email a PDF from Acrobat, it uses a background MAPI connection to generate the email draft. If this integration is outdated, blocked by security software, or if Outlook isn't set as the default client, Acrobat fails to pull the auto-complete cache.
Where are suggested contacts stored in Outlook 2010?
Outlook 2010 stores suggested contacts in an Auto-Complete List cache file, typically with an .nk2 extension. External programs like Acrobat need proper read access to this cache file to display suggestions.
Does upgrading from Outlook 2010 fix integration issues with modern Acrobat versions?
Yes, Outlook 2010 is an older, unsupported version of the software. Upgrading to a newer mail client can resolve underlying compatibility and security conflicts with recent updates to Acrobat DC.
