Degradation of E5 License for Meeting Room Lab work --> Offce 365 Dev Tenant

Dear Community, I just got a message in the Teams Admin Center, that Meeting Room Devices will no longer supported for sign-In with the E5 License and we are forced to switch to the new Basic or Pro License. The Office 365 Dev Tenant is broadly used for Lab/Testing work.

Microsoft: Please check internally, how you can provide the basic AND Pro License in the Dev Tenant Subscriptions, so we can continue our Knowledge investment in the Microsoft Platform

many thanks

Andy
