Sensitivity labels and Microsoft 365 containers

Decisions uses roster groups to store tasks in private Team channels

 If your organization uses mandatory sensitivity labels for Microsoft 365 groups (Containers including Teams and Microsoft 365-connected SharePoint sites); your IT administrator should ensure that roster containers are exempt from this requirement. Or that mandatory sensitivity labels have a default value that is always applied to roster containers when created.
