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Ad blockers, strict privacy extensions, pop-up blockers, and sometimes even outdated versions of the official Office extension can cause a blank tab loop by preventing the web application from executing necessary scripts.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.
