Reporting a Problem

You do not need to report the Outlook.com HTTP 500 error separately if Microsoft’s service-health page shows an active Outlook.com incident with the same access symptoms.

1. Open the Microsoft Service Health Status page.
2. Expand Microsoft’s Consumer Products.
3. Select Outlook.com and review the current incident and updates. Microsoft specifically directs Outlook.com access problems to this page.^1^
4. If an active incident covers mailbox or web-access failures, wait for Microsoft to mark it resolved, then refresh Outlook.com or sign out and back in.

The screenshot’s HTTP ERROR 500 is consistent with errors reported by other Outlook.com users during Microsoft-side service incidents.^2^

When to report it

Contact Outlook.com Support if either condition applies:

• Service Health does not show an Outlook.com incident, but the error continues.
• Microsoft marks the incident resolved, but your mailbox still produces HTTP 500 after allowing time for recovery.

If Outlook.com opens, select Help on its menu bar, enter the problem, and then choose Still need help? → Yes. If you cannot sign in or open the mailbox, use the alternative contact option under Still need help? on Microsoft’s support page.^3^

When reporting it, include:

• The screenshot
• The exact time and time zone
• HTTP ERROR 500
• Whether the Outlook mobile or desktop app is also affected
• Whether the service-health incident was already marked resolved
