Manage tenants by using deployment insights in Microsoft 365 Lighthouse

Microsoft 365 Lighthouse provides deployment insights within and across the tenants you manage. The single view lets you:

Understand the deployment status across all tenants, users, and tasks.
Review deployment exceptions such as Dismissed tasks and Excluded users.
Review regressions such as tasks the change from a Compliant or Dismissed status to a status of Not compliant or Not licensed.
Quantify threats based on user- and task-level deployment progress.
Prioritize deployment activities based on risk.

Manage deployment progress by using deployment insights

In the left navigation pane in Lighthouse, select Deployment > Deployment insights.
On the Deployment insights page, review the following areas to gather insight on your tenants' deployment progress.

Area	Description
Tenant progress	Provides deployment progress summary across all tenants. You can hover over the graph to see the number of tenants with deployment plans that are Complete and Not complete. Tenants for which all tasks are Compliant or Dismissed are Complete. Tenants for which one or more tasks are Not compliant or Not Licensed.
User progress	Provides user deployment progress summary for all users. You can hover over the graph to the exact number of users that are Complete and Not complete. Users for whom all tasks are Compliant, Dismissed, or Not targeted are Complete. Users for whom one or more assigned tasks is Not compliant or Not Licensed.
Tenants tab	Provides detailed deployment progress for each tenant. You can use various data points from the table to determine the appropriate action. For example, the Not licensed tasks column indicates the number of tasks for which the tenant is not licensed. To resolve the issue, you can add a license or exclude the user from the task. The Regressed tasks column indicates a task status changed from a Compliant or Dismissed state. You can go to the specific tenant deployment plan and take the appropriate action.
Tasks tab	Provides deployment progress for all tasks, including how many tenants the task is assigned to. For tasks that are Not compliant or Not licensed, you can take action to resolve the issue.

For additional solutions for common deployment issues, see Deploying baselines section in Microsoft 365 Lighthouse frequently asked questions (FAQs).

In the left navigation pane in Lighthouse, select Deployment > Deployment insights.
From the Tenants list, review tenants with regressed tasks indicated by the Regressed tasks column.
Select the desired tenant to see specific regressed tasks.
Select View tenant deployment plan to navigate you to the tenant's deployment plan.
From the Deployment plan tab, select the regressed task from the list.
Review the tenant's configuration and, depending on the regression scenario, modify the deployment task, modify the tenant's configuration, modify the tenant's licensing, or dismiss the task to resolve the regression.

Every dismissed task and excluded user represent a potential threat. You can audit these exceptions to ensure they still meet your requirements.

In the left navigation pane in Lighthouse, select Deployment > Deployment insights.
From the Tenants list, select the tenant with a dismissed task.
From the tenant details pane, select the Dismissed tasks tab.
From the list, review the reason and justification sections to determine if a task dismissal is still valid.
If no longer valid, select the task from the list and then select Reinstate.

In the left navigation pane in Lighthouse, select Deployment > Deployment insights.
From the Tenants list, select the tenant with an Excluded user.
From the tenant details pane, select the Excluded users tab.
From the task list, expand each task and determine if the listed user should still be Excluded.
If a user should no longer be excluded, select View tenant deployment plan.
From the tenant's Deployment plan tab, select the applicable deployment task.
From the task details pane, select Deploy. The deployment wizard is launched.
On the Review deployment task page, remove the user from the Excluded users field.
Select Next.
Select Exit Wizard.
