Many organisations approach Microsoft 365 Copilot as a licensing project. They decide who should receive access, identify use cases, arrange training, and prepare teams to work differently. I would begin even before Copilot is introduced, when the organisation needs to understand what users can already see across Microsoft 365.
Copilot works within the permissions a user has. If an employee can reach an open SharePoint site, a broadly shared folder, or information left accessible after a role change, Copilot can make that content easier to find and use.
The tenant carries its history
Microsoft 365 environments change constantly. People join and leave, teams are restructured, projects end, and collaboration spaces are created. Access is often granted quickly because work needs to continue, while reviews happen far less consistently.
Over time, permissions can drift away from current responsibilities. A document shared with a broad group may remain open long after the need has passed. SharePoint sites can accumulate members, and sensitive files may sit in locations where their classification no longer reflects their content.
Copilot can surface information from the areas a user is entitled to access. That makes tenant hygiene a practical part of AI readiness. Businesses need a clear view of oversharing, stale permissions, and whether sensitive information is being handled in line with policy.
Governance has to come before scale
A controlled Copilot rollout depends on more than assigning licences. The organisation needs identity controls that reflect current roles, a clear approach to classification, Data Loss Prevention policies that match the risk environment, and visibility over how information is shared.
Microsoft Purview can support this work through sensitivity labels, DLP, information governance, and oversight of data use. These controls still need to be configured around the organisation’s environment. Technology does not remove the need for policy ownership, regular review, and clear accountability.
POPIA adds another layer of responsibility for South African businesses. Employee records, customer information, financial documents, and other personal information may already sit across Microsoft 365. Introducing Copilot increases the urgency of confirming who can access that information and how it is protected. A safer rollout begins with understanding that exposure before users start asking AI to retrieve, summarise, or draft from business data.
E5 can provide a stronger control layer
For organisations that need broader identity, security, and governance capability, Microsoft 365 E5 can provide a stronger foundation for Copilot adoption.
Its value lies in bringing together controls across identity protection, Microsoft Defender, sensitivity labelling, and Purview DLP. This gives the business a structured way to address oversharing, strengthen access, and govern sensitive information before Copilot is introduced more widely.
Licensing alone does not resolve poor permissions or unclassified information. The environment still needs to be assessed, remediated, and reviewed. E5 provides the capability, while the quality of the rollout depends on how those capabilities are applied.
Readiness is practical work
A readiness process should examine the tenant as it operates today. That includes reviewing oversharing, checking permissions, identifying gaps in identity and security controls, and understanding what remediation is needed before deployment.
The result should be a prioritised plan rather than a vague recommendation to improve governance. Some organisations may need to tighten access to specific SharePoint sites. Others may need better sensitivity labels, stronger DLP policies, or clearer ownership of data and permissions.
Adoption also needs attention. Once the environment is ready, employees need guidance on how to use Copilot responsibly in real workflows. A secure foundation creates the conditions for adoption, but people still need to understand where the technology is useful and where judgement remains essential.
IPT’s E5 and Copilot readiness assessment gives businesses a practical view of what stands between their current Microsoft 365 environment and a controlled rollout. It covers oversharing, identity, governance, licensing, and the work needed to close the most important gaps.
Copilot can help people work more effectively, but confidence begins before the first licence is assigned. It begins with knowing what users can already see and making sure that access still belongs there.
