- Scenario
- Attempting to use the Adobe PDFMaker integration or Acrobat add-in to process documents within Microsoft Outlook.
- Observed behavior

Upgrade to a Supported Version of Adobe Acrobat
Since Acrobat XI is an end-of-life (EOL) product, upgrading to a currently supported version of Acrobat is the most reliable way to restore Outlook integration and ensure system security.
Adobe Acrobat XI no longer receives updates or security patches. Recent Windows and Microsoft Office updates have rendered it incompatible, which causes the PDFMaker add-in to fail or remain inactive.
Open the Windows Control Panel, select 'Programs and Features', locate Adobe Acrobat XI Pro in the list, and click 'Uninstall'.
Navigate to the official Adobe website to purchase or download the latest version of Adobe Acrobat or Adobe Acrobat Reader.
Follow the on-screen prompts to install the new software. Once installed, open Microsoft Outlook and check the ribbon to confirm the new Acrobat add-in has successfully loaded.
Manually Enable the PDFMaker Add-in in Outlook
You can try to manually force the Acrobat PDFMaker add-in to activate from within Outlook's options, although this may not be a permanent fix for EOL software.
Handle Your Documents Seamlessly with WPS Office
If third-party add-in compatibility issues in Microsoft Office are slowing down your workflow, consider switching to WPS Office. It provides robust, built-in tools for handling PDFs, Word documents, spreadsheets, and presentations in a single, lightweight application.
- 1. Download and Install: Download WPS Office Free from the official website and run the installer on your computer.
- 2. Open Your Files: Launch the application and seamlessly open your existing Word, Excel, PowerPoint, or PDF documents.
- 3. Use Integrated PDF Features: Enjoy powerful built-in PDF viewing, editing, and format conversion features without needing to configure complex external COM add-ins.
Frequently Asked Questions
Why did my Acrobat Pro XI add-in suddenly disappear from Outlook?
Adobe Acrobat XI has reached its End-of-Life (EOL), meaning it no longer receives compatibility or security updates. Recent updates to Microsoft Office or Windows likely caused a compatibility conflict, forcing Outlook to disable the outdated add-in.
Is it possible to force Outlook to permanently load the Acrobat XI PDFMaker add-in?
You can attempt to re-enable it by navigating to File > Options > Add-ins > Manage COM Add-ins and checking the PDFMaker box. However, because Acrobat XI is fundamentally incompatible with newer Office builds, Outlook may continue to automatically disable it to prevent software crashes.
Is it safe to continue using Adobe Acrobat Pro XI for offline tasks?
No, it is highly discouraged. Because Acrobat XI no longer receives technical support or security patches from Adobe, continuing to run it on your system leaves your computer exposed to known vulnerabilities, even for offline tasks.
Do I absolutely need an Adobe add-in to save Outlook emails as PDFs?
Not necessarily. Modern versions of Windows feature a built-in 'Microsoft Print to PDF' virtual printer. You can easily save an email as a PDF by opening the email, pressing Ctrl+P, and selecting 'Microsoft Print to PDF' as your target printer.
