Microsoft will soon be increasing Microsoft Teams team membership limit to 10 thousand members.
Microsoft will begin enabling this for all tenants at the end of April and will be complete at the end of May.
This message is associated with Microsoft 365 Roadmap ID 62549
How does this affect me?
Once available, all new and existing teams can host up to 10 thousand members. Increase in team size will help you utilise teams for scenarios such as company wide, department wide and inter-departmental communications.
What do I need to do to prepare for this change?
No explicit action is needed from admins and both new and existing teams will be able to grow to 10,000 members.
