Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi FredLea,
Based on my understanding, you don't have to remove the Business Premium licenses as it's expired. You have the new E3 licesne which will let you continue to use those Office 365 services. The expired subscription may be automatically deleted after centern days. You can just ignore the expiration notification for Business Premium licenses. To learn more, see What happens to my data and access when my Office 365 for business subscription ends?
Best regards,
Tim
