Links from Word to pdf doc online not working

Try to check and fix the following:

1. Set default browser by protocol
• Windows Settings → Apps → Default apps → choose your browser → click Choose defaults by protocol → ensure HTTP and HTTPS are associated with that browser.
2. Confirm PDF file association
• Windows Settings → Apps → Default apps → search for .pdf → ensure Adobe Acrobat Reader (or your preferred PDF app) is selected.
3. Reset browser and PDF defaults
• In Default apps, scroll to Reset to the Microsoft recommended defaults, then reassign your preferred browser and PDF app.
4. Repair Office and Acrobat
• Control Panel → Programs → Microsoft 365 (or Office) → Modify → Quick Repair (if that fails, try Online Repair).
• Do the same for Adobe Acrobat Reader (Modify/Repair).
5. Check Word Trust Center and hyperlink behavior
• Word → File → Options → Trust Center → Trust Center Settings → Protected View: try temporarily disabling Protected View for files from the Internet to test (re-enable after testing).
• Word → File → Options → Advanced → under Editing options, ensure Use CTRL + Click to follow hyperlink is as expected.
6. Test a different browser as default
• Temporarily set Chrome/Edge/Firefox as the default and try the link from Word to isolate whether the problem is the browser registration.
7. Check for extensions or policies
• Disable any Word add-ins that might intercept links: Word → File → Options → Add-ins → COM Add-ins → Go → uncheck suspicious add-ins and restart Word.
• If company-managed device, check with IT for group policies that may block URL handling.
8. Try creating a new hyperlink type
• In Word, insert a hyperlink and explicitly start with “https://” (not a file path). If link was added as a file:// URL, change it to https://.
9. Registry troubleshooting
• If comfortable: verify HKEY_CLASSES_ROOT\http and \https point to correct handlers and that the browser’s ProgID exists.
