How to Fix Outlook Freezing When Sending PDF from Acrobat Pro
Question details
User experiences application freezing or unresponsiveness in Microsoft Outlook when trying to email a PDF directly using the Email button in Adobe Acrobat Pro DC.
- Product
- Microsoft Outlook and Adobe Acrobat Pro DC
- Device & OS
- Windows
- Scenario
- Using the 'Email' button within Adobe Acrobat Pro DC to automatically generate a new email in Microsoft Outlook with the active PDF attached.
- Observed behavior
- Microsoft Outlook stops responding and freezes, especially common after the user upgrades their Microsoft 365 installation from a 32-bit version to a 64-bit version.
Ensure you have saved all open documents and completely closed both Microsoft Outlook and Adobe Acrobat Pro via the Windows Task Manager before proceeding with any repairs.
Update Applications and Match Architecture Versions
Resolves system integration conflicts caused by running mismatched architectures, such as 32-bit Acrobat attempting to integrate with a 64-bit version of Microsoft Office.
When upgrading Microsoft 365 to 64-bit, third-party integrations like the Acrobat PDFMaker can break if they remain on a 32-bit architecture. Aligning the versions restores normal functionality.
Open Outlook, go to File > Office Account > About Outlook, and check if it explicitly says 64-bit.
If you upgraded Microsoft 365 to 64-bit, download and reinstall the 64-bit version of Adobe Acrobat Pro DC to match.
Open Adobe Acrobat Pro, click on the Help menu, and select 'Repair Installation' to fix the PDFMaker integration components.
Restart your computer to ensure all background registry and integration updates are applied correctly.
Launch Outlook in Safe Mode and Isolate Add-ins
Helps determine if the freezing is caused by a corrupted or conflicting third-party add-in within Outlook rather than Acrobat itself.
Use Manual File Attachment Workaround
A quick and reliable way to bypass the integration failure when you need to send a document urgently.
Avoid Integration Crashes with WPS Office
If Microsoft Outlook and third-party integrations continue to freeze your workflow, consider switching to WPS Office. WPS offers a built-in, lightweight PDF suite alongside robust document editing capabilities, bypassing the need for clunky add-ins.
- 1. Install WPS Office: Download and install the free WPS Office suite from the official website.
- 2. Open Your PDF: Launch WPS PDF to read or edit your document natively.
- 3. Share Instantly: Use the Share tool on the main ribbon to quickly attach the document to an email without relying on heavy third-party integrations.
Frequently Asked Questions
Why does Microsoft Outlook freeze when I use the email button in Acrobat?
This commonly happens due to a mismatch in system architectures, such as upgrading Microsoft Office to 64-bit while Adobe Acrobat remains on a 32-bit version. It can also be caused by outdated integration add-ins (PDFMaker) or conflicting third-party extensions in Outlook.
How can I check if my Microsoft Outlook installation is 32-bit or 64-bit?
Open Microsoft Outlook, click on 'File', then select 'Office Account'. Click the 'About Outlook' button. At the top of the dialog box that appears, you will see the full version number ending in either '32-bit' or '64-bit'.
Is there a way to email my PDF if the Acrobat integration is completely broken?
Yes. Instead of using the email button inside Acrobat, save your PDF to a known folder on your computer. Then, open your email client, compose a new message, and manually select 'Attach File' to browse and upload your saved document.
