what happen on outlook today?

The HTTP 500 page shown is likely part of the Outlook/Microsoft 365 service disruption reported on November 12–13, 2026, so check Microsoft’s service status and wait for service restoration before changing your browser or account settings.^1^

What to do now

1. Open the Microsoft Service Health Status page.
2. Expand Microsoft consumer products → Outlook.com.
3. If Outlook.com is degraded, no local repair is required. Wait for Microsoft to mark it healthy, then reload Outlook. Microsoft specifically directs Outlook.com users with access problems to this status page.^2^
4. Avoid repeatedly changing your password—the screenshot shows that the Outlook website cannot process the request, not an incorrect-password message.

If service status is green

Test Outlook in a Chrome Incognito window (Ctrl+Shift+N):

• It works in Incognito: Clear Outlook/Microsoft cookies and cached data for all time, close Chrome, and sign in again.
• It still fails: Try another browser, the Outlook mobile app, or another network. If all methods show the same error, it is more likely a service or mailbox-side problem than a Chrome cache problem.

Incognito testing, clearing browser data, and trying another browser are established isolation steps for Outlook.com HTTP 500 errors.^3^
