Run Microsoft 365 Quick or Online Repair
Use the built-in Windows repair tool to fix corrupted Microsoft 365 installation files that may be causing the application launch to default to a blank browser tab.
A damaged Microsoft 365 installation can disrupt the file handling process, pushing the request to a browser instead of the local application. Running the built-in repair utility is the safest first step.
Open Windows Settings, navigate to 'Apps' in the left sidebar, and click on 'Installed apps'.
Scroll down the list to find 'Microsoft 365', click the three-dot menu icon next to it, and select 'Modify'.
Select the 'Quick Repair' option and click 'Repair' to begin the process. This takes a few minutes and does not require an internet connection.
If the blank tab issue persists after Quick Repair, repeat the previous steps, select 'Online Repair', and restart your computer upon completion.

Check Chrome Pop-up Permissions and Disable Extensions
Browser restrictions or conflicting Chrome extensions can interfere with Microsoft 365 web apps and prevent them from opening properly.
Uninstall and Reinstall Microsoft 365
If repair options and browser troubleshooting fail, a clean uninstallation and reinstallation of Microsoft 365 can resolve deep-rooted software conflicts.

Frequently Asked Questions
Why does Microsoft 365 keep opening in a browser instead of the desktop app?
This happens if your default file associations in Windows are set to your web browser instead of the Office desktop applications, or if the Office browser extension is intercepting the command to open the file locally.
Can I force Microsoft Office documents to open in the desktop app?
Yes. If you are using the Microsoft 365 web portal, go to the top settings menu and choose to open links in the desktop app. In Windows, you can go to Settings > Apps > Default apps to associate .docx, .xlsx, and .pptx files directly with the Microsoft desktop applications.
What Chrome extensions commonly interfere with Microsoft 365?
Ad blockers, strict privacy extensions, pop-up blockers, and sometimes even outdated versions of the official Office extension can cause a blank tab loop by preventing the web application from executing necessary scripts.
Will running Microsoft Online Repair delete my Office files?
No. Repairing Microsoft 365 only fixes the application's executable files and registry entries. It will not affect your saved documents, presentations, spreadsheets, or personal data.
