Microsoft Teams group chats can be significantly larger starting this month. A new update is rolling out now that increases the maximum number of group chat participants from 100 to 250. Petri reports that the update will be available to all Microsoft Teams tenants by mid-May, pointing toward the Microsoft 365 roadmap.
Large group chats in Microsoft Teams have a few settings that make them easier to manage. For example, any chat with more than 20 people turns off Outlook automatic replies and Teams status messages, typing indicators, video and audio calling, and read receipts.
Unfortunately, admins cannot limit a chat's group size, meaning that a group chat can grow to exceed the maximum capacity for calls.
Microsoft Teams has experienced unprecedented growth during the current global health crisis. With more people working from home, Microsoft Teams skyrocketed to 75 million daily active users. Microsoft continues to add features to Teams, including several that help people having to work from home in larger numbers. Teams recently increased the number of people you can view on your screen at once from four to nine.
