How to Open Exported Word PDFs in Adobe Reader Instead of a Browser
Product
Microsoft Word
Device & OS
Windows
Scenario
Exporting a Word document to PDF and automatically opening the published file for review.
Observed behavior

Before you start

Ensure that Adobe Reader or Adobe Acrobat is installed on your computer and updated to the latest version before modifying your Windows file associations.

Solution 1Recommended

Set Adobe Reader as the Default PDF App via the Context Menu

The quickest way to fix this issue is by changing the default program for PDF files directly from the Windows right-click context menu.

Microsoft Word relies on your operating system's default file association to decide which program opens a PDF after publishing. By changing this default setting, Windows will redirect all PDF opening requests to Adobe Reader.

1
Locate a PDF file

Find any existing PDF file on your computer using Windows File Explorer.

2
Open the Open with menu

Right-click the PDF file, hover over 'Open with' in the context menu, and select 'Choose another app'.

3
Select Adobe Reader

Click on Adobe Acrobat or Adobe Reader from the list of available applications.

4
Apply permanently

Check the box that says 'Always use this app to open .pdf files' (or click 'Always' in Windows 11) and click OK.

Set Adobe Reader as the Default PDF App via the Context Menu
Test the Export: Return to Microsoft Word and export your document again with 'Open file after publishing' enabled. It should now launch directly in Adobe Reader.

Frequently Asked Questions

Why does Windows keep changing my default PDF app back to Microsoft Edge?

Windows updates, Edge browser updates, or strict organizational IT policies can sometimes reset file associations. If you are on a company computer, check with your IT administrator to see if a policy is enforcing Microsoft Edge as the default PDF viewer.

Does this issue happen because my files are synced with OneDrive or SharePoint?

No, the browser issue is strictly related to how Windows handles the .pdf file extension association locally. Whether your original Word files are backed up locally, on OneDrive, or SharePoint does not impact the PDF export behavior.

What does 'Open file after publishing' mean in Word?

It is a checkbox option in the Export to PDF dialog that commands Windows to immediately open the newly created PDF file using the system's default PDF viewer, allowing you to quickly review the exported document.
