A content item sharing and synchronization system providing team shared folders is described. Users of the system have access to the team shared folder simply by being a member of a team. A team account manager of the team can grant access to the team shared folder simply by inviting selected users to the team. Similarly, the team account manager can revoke access to the team shared folder simply by removing a user from the team. Unlike typical network file server folders, separate access control list management for the team shared folder apart from user team membership management is not needed to grant and revoke access to the team shared folder, thereby reducing administrative steps necessary to effectively manage access to the team shared folder.
