Hello @Jessica M
The email you received from Microsoft indicates that your Microsoft Entra ID tenant has been inactive for over 200 days. This is a reminder to take action regarding your tenant's inactivity.
To avoid any service disruptions, it's recommended that you make a purchase or renew your existing subscriptions before the deadline of June 06, 2025. This will ensure that your tenant remains active.
For clarification regarding the Entra ID tenant, a Microsoft Entra tenant provides identity and access management (IAM) capabilities for the applications and resources used by your organization. An identity represents a directory object that can be authenticated and authorized to access resources. These identity objects include human identities (such as students and teachers) as well as non-human identities like classroom and student devices, applications, and service principals.
The Microsoft Entra tenant serves as an identity security boundary under the control of your organization’s IT department. Within this boundary, the administration of objects (such as user objects) and the configuration of tenant-wide settings are managed by your IT administrators.
If you're already using services like Microsoft 365, Office 365, Azure, or Dynamics CRM Online, your tenant is automatically a Microsoft Entra tenant. You can start managing access to your integrated cloud apps right away. For additional information refer these documents:
