The Microsoft Word Login Page won't load and keeps timing out

Microsoft currently reports a Microsoft 365 service degradation that can prevent connections to multiple services, so wait for service recovery and monitor the official status page before repairing or reinstalling Word.^1^

What to do now

1. Check Microsoft service health for incident updates.^2^
2. Leave Word open only if working offline; otherwise, close it and retry signing in after Microsoft reports recovery.
3. Test the Microsoft 365 portal in a browser.^3^
   • If that page also times out, the current service incident is the likely blocker.
   • If the portal loads but Word still cannot display its sign-in page after service recovery, continue below.

If Word still cannot sign in after recovery

Run Microsoft's automated sign-in diagnostics on the affected Windows PC:

1. Open Start, search for Get Help, and launch it.
2. Enter sign in to Microsoft Office in the search box.
3. Follow the recommended steps.
4. If no sign-in problem is detected, search for Microsoft 365 network connectivity test and run that test. It checks connectivity from the PC through to Microsoft's network.^4^

If the network test identifies a proxy or firewall problem, ensure the network allows outbound Microsoft 365 authentication traffic over TCP ports 80 and 443. Microsoft documents network restrictions and authentication proxies as possible causes of Office sign-in failures.^5^

Avoid clearing credentials, uninstalling Office, or editing the registry while the service incident remains active; those actions will not resolve a Microsoft-side outage.
