100% Microsoft 365
Strong Microsoft 365 governance is not about maximising rules. It is about explicit ownership, standards, lifecycle, decision rights and controlled exceptions across Teams, SharePoint, Microsoft 365 Groups, Entra, Purview and Copilot.

In short
A workable governance model connects ownership and decisions to technical controls, lifecycle processes, measurable exceptions and periodic review. That keeps Microsoft 365 governable as the organisation grows, merges, introduces AI or works with multiple suppliers.
For decision-makers and platform teams
Operating model
A governance document without accountable owners quickly becomes shelfware. The foundation is an operating model that connects strategic, functional and technical responsibility.
PEXOR typically separates strategic direction and risk appetite, tactical product and platform steering, and operational execution. This makes it clear who sets standards, who assesses change and who owns day-to-day controls.
For larger organisations, the exception process is as important as the standard. Every deviation should have an owner, rationale, review date and exit path.
Teams, SharePoint & Groups
Teams, SharePoint sites and Microsoft 365 Groups are tightly connected. Governance therefore has to cover creation, ownership, use, review and end of life as one chain.
Provisioning should not stop when a Team or site is created. Ownership, classification, guest access, retention and periodic review belong in the same lifecycle.
Microsoft provides governance and lifecycle capabilities across Groups, Teams and SharePoint. The right control level depends on risk, licensing and how much self-service the organisation wants.
Policy to engineering
A rule such as ‘no uncontrolled external sharing’ only becomes operational when the technical setting, monitoring and owner are defined.
PEXOR maps policy to configuration standards, reporting, review moments, logging and remediation. Each control should be intentionally preventive, detective or exception-based.
This also improves auditability: not just the target state is documented, but how drift is detected, who reviews it and how quickly it is corrected.
AI-ready governance
Microsoft Copilot respects existing access permissions. Existing oversharing, stale access and poorly governed information can therefore become more visible in AI experiences.
A Copilot programme should start with governable access, information architecture, lifecycle, classification and monitoring rather than with prompts or licences.
For many organisations, this is the right moment to simplify governance: fewer disconnected policy documents and more concrete, demonstrable controls.
