View tenant service health in Microsoft 365 Lighthouse

You can view service health for the tenants you manage in Microsoft 365 Lighthouse. Service health includes incidents and advisories for several services, including Microsoft Intune, Microsoft Entra identity services, and mobile device management (MDM) cloud services. You can also see how many of your managed tenants are affected by incidents. For example, if one of your tenants is experiencing problems, you can check the Service health page to determine whether it's a known issue with a resolution in progress or whether a recent change may be impacting them. This could save you time troubleshooting and reduce support calls.

If you can't sign in to Lighthouse, you can use the Microsoft 365 service health status page to check for known issues preventing you from logging in to your partner tenant. Also, sign up to follow @MSFT365status on Twitter to see information on specific service incidents.

Before you begin

To view service health, you'll need a Microsoft Entra role in the partner tenant with the following property set: microsoft.office365.serviceHealth/allEntities/allTasks. For a list of Microsoft Entra roles, see Microsoft Entra built-in roles.
