Now that Microsoft has launched its Teams Premium service, it’s shaking up the free offering for work — and not everyone will be happy. The company is retiring the existing Teams Free version for small business in favor of the similarly-titled Teams (free) on April 12th, and legacy data won’t carry over. Your office will have to pay for at least the Teams Essentials plan ($4 per user per month) to preserve chats, meetings, channels and other key info.
