Frequently Asked Questions

Will reinstalling Microsoft 365 delete my Word or Excel files?

No. Reinstalling the Microsoft 365 application only removes the software files. It does not delete your personal documents, whether they are stored locally on your hard drive or synced in OneDrive.

Why do individual Office apps work when the main app is blank?

The main Microsoft 365 access window relies on specific web components (such as Edge WebView2) to display its dashboard interface. If these components are outdated, blocked, or corrupted, the dashboard fails to load, but the standalone applications like Word and Excel are unaffected because they run independently.

Can I still access my recent files without using the Microsoft 365 app?

Yes. You can bypass the main dashboard by opening Word, Excel, or PowerPoint directly from your Windows Start menu. Once open, you can view and access your recent files from within those specific applications.
