The Penn State tenant is an organization you’re a member of, not one you own, so it can’t be deleted from the dashboard. It can only be left.
Use the Entra admin center to leave that organization:
- Go to https://entra.microsoft.com and sign in with the Microsoft account that shows the Penn State tenant.
- In the top menu, open Settings → Directories + subscriptions → Manage tenants.
- In the tenants list, locate the Penn State organization.
- Select the checkbox next to that organization and choose Leave.
After leaving, that tenant will no longer appear in the tenant list for that account.
