Microsoft Teams Governance Framework 2026

Microsoft Teams Governance Framework Enterprise (2026)

Microsoft Teams governance is the operational discipline that prevents Microsoft Teams from becoming a chaotic sprawl of unmanaged Microsoft 365 Groups, files no one labels, external collaborators no one offboarded, and Microsoft 365 Copilot grounding noise that degrades search quality.

EPC Group has delivered Microsoft Teams governance for Fortune 500 organizations since the Microsoft Teams general availability era.
