Solution 1Recommended

Check Microsoft 365 Service Status

Verify if the loading issue is caused by a temporary server outage on Microsoft's end.

If Microsoft's servers are experiencing downtime or degraded performance, web-based applications like Word, Excel, and Outlook will fail to load in any browser. Checking the service status helps you determine if you need to wait for a server-side fix.

1
Visit the Status Page

Open a new tab and go to the official Microsoft 365 Service Health Status page.

2
Check Application Status

Look for any reported outages, alerts, or degraded performance specifically for Word, Excel, or Outlook on the web.

3
Wait for Resolution

If there is an active outage listed, you will need to wait until Microsoft resolves the server-side issue before documents will load again.

Frequently Asked Questions

Why is my Microsoft 365 document stuck on the loading screen?

This typically occurs due to corrupted browser cache data, interfering browser extensions (such as ad blockers or script blockers), or a temporary server outage on Microsoft's end preventing the web application from fully loading.

Will clearing my browser cache delete my Microsoft 365 files?

No, clearing your browser's cache and cookies only removes temporary internet files stored locally on your device. Your Microsoft 365 documents are safely stored in the cloud on OneDrive or SharePoint.

How can I access my documents if Microsoft 365 is down?

If the Microsoft 365 web version is experiencing an outage, you can use installed desktop applications like WPS Office or the Microsoft Office desktop apps to open and edit locally synced copies of your files.

Which browser is best for Microsoft 365 web apps?

Microsoft 365 is optimized for modern browsers including Microsoft Edge, Google Chrome, Mozilla Firefox, and Apple Safari. Keeping your preferred browser updated to the latest version ensures the best performance and compatibility.
