Enable Acrobat PDFMaker via Outlook Add-ins Settings

Often, the add-in remains installed on your system but has been disabled by Office for performance reasons. You can re-enable it manually from the Outlook settings.

Microsoft Office sometimes automatically disables third-party add-ins if it detects they are slowing down the application's startup time. Checking your COM Add-ins list is the fastest way to resolve this.

1
Open Outlook Options

Launch Microsoft Outlook and click on the 'File' tab in the top-left corner, then select 'Options'.

2
Navigate to Add-ins

In the Outlook Options window, click on 'Add-ins' on the left sidebar to view all active and inactive application add-ins.

3
Manage COM Add-ins

At the bottom of the window, ensure 'COM Add-ins' is selected in the 'Manage' dropdown menu, then click the 'Go' button.

4
Enable PDFMaker

Locate 'Acrobat PDFMaker Office COM Addin' in the list, check the box next to it, and click 'OK'.

5
Restart Outlook

Close Microsoft Outlook and reopen it to apply the changes and ensure the PDFMaker tab appears on your ribbon.

Enable Acrobat PDFMaker via Outlook Add-ins Settings
Check Disabled Items: If you do not see PDFMaker in the COM Add-ins list, change the 'Manage' dropdown to 'Disabled Items' and click 'Go'. If it appears there, select it and click 'Enable' before repeating the steps above.

Frequently Asked Questions

Why did PDFMaker disappear after renewing my Acrobat subscription?

When subscriptions are renewed or software is updated in the background, Microsoft Office may flag the PDFMaker add-in as a new or modified extension and temporarily disable it to optimize Outlook's load times. Re-enabling it in the COM Add-ins menu usually resolves the issue.

Is Acrobat XI fully compatible with Office 365?

Adobe Acrobat XI is an older version of the software that reached end-of-support in 2017. While it may still function on older systems like Windows 7, you might experience ongoing add-in compatibility issues with frequently updated software like Office 365.

What should I do if PDFMaker refuses to stay enabled in Outlook?

If you enable the add-in but it disables itself upon restarting Outlook, you may need to run Outlook as an administrator. Right-click the Outlook shortcut, select 'Run as administrator', go to File > Options > Add-ins, enable PDFMaker, and close Outlook. The setting should now be saved in the Windows Registry.
