Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Anderson370,
Good day! Thank you for your quick response to Microsoft Community
As per your first query, I would say no, you cannot. If you delete a user, then that user will delete, and the license will be counted as a unassign license. You can assign that license different user. You can reduce assign license quantity, but overall license quantity will be same.
Secondly, I would also say, no, you cannot avoid paying for unassigned licenses. No matter how many licenses you have used/assigned. You have to pay what you have purchased.
For more details related to billings/subscription, you may contact our billing business support Get support - Microsoft 365 admin | Microsoft Learn****
