Search for users in Microsoft 365 Lighthouse

Microsoft 365 Lighthouse lets you search for a specific user across all active tenants. This allows you to find a user quickly without needing to navigate different tenants.

  1. In the left navigation pane in Lighthouse, select Users > Account management.

  2. On the Search users tab, enter all or part of a display name or user principal name (UPN) in the search box.

  3. From the search results list, select a user to open the user details pane.

Next steps

Once the user is found, you can reset their password, block their account, or delete their account. For more information, see Reset user password or Block user sign-in in Microsoft 365 Lighthouse.
