Sign up for Microsoft 365 Lighthouse

This article provides instructions for how to sign up for Microsoft 365 Lighthouse. Microsoft 365 Lighthouse is an admin portal that helps Managed Service Providers (MSPs) grow their business and deliver managed services at scale for small-and medium-sized business (SMB) customers. Lighthouse provides multi-tenant views across customer devices, data, users, and sales opportunities to help customers get the most value from Microsoft 365.

Before you begin

  • Microsoft 365 Lighthouse is deployed in the partner tenant only—not in the customer tenants, but make sure you and your tenants meet the requirements listed in Microsoft 365 Lighthouse requirements.

  • You must be a Global Administrator in the partner tenant that you're signing in to.
